MDaemon Email Settings: IMAP, SMTP and POP3

MDaemon runs on your own Windows server, so the mail host is your MDaemon address like mail.yourdomain.com. The ports are the same on every MDaemon: IMAP 993, POP3 995, SMTP 465 or 587. Copy each value with 1 tap.

MDaemon Quick Settings

IMAP Server mail.yourdomain.com
IMAP Port 993 (SSL/TLS)
SMTP Server mail.yourdomain.com
SMTP Port 465 (SSL) / 587 (STARTTLS)
POP3 Server mail.yourdomain.com
Username Your full email address

Quick answer: for MDaemon the mail server is your own host, usually mail.yourdomain.com. IMAP is port 993 with SSL/TLS. SMTP is port 465 (SSL) or 587 (STARTTLS). POP3 is port 995 with SSL. Sign in with your full email address and your MDaemon account password. MDaemon Webmail sits on a separate address, mail.yourdomain.com:3000, which is a web page, not a mail port.

Every setting on this page is verified with live IMAP and SMTP connections from Univik email software. We build email backup and converter tools since 2013, so we test against these servers every day. See what changed →

What Changed Recently#

MDaemon is steady across releases, but a few points matter when you connect a client. Here is the current status.

Latest update

WorldClient is now called MDaemon Webmail. The webmail still answers on port 3000, so older guides that say WorldClient mean the same page. The mail ports for Outlook and phones did not change.

Earlier change

Two factor sign in brings app passwords. If two factor is on for an account in Webmail, mail apps that cannot show the second prompt need an app password made in Webmail. Without two factor, your normal password works.

Earlier change

ActiveSync and MDaemon Connector stay the way to sync more than mail. IMAP moves mail. To pull calendar, contacts and tasks onto a phone or into Outlook, MDaemon uses its ActiveSync add on or the MDaemon Connector.

Current status: the client ports are the same on every MDaemon. Your mail host is whatever your admin set, usually the same base address as your Webmail without the 3000.

Before You Begin#

Do these 2 things first. Miss either one and the app is refused even with perfect server values.

1. Know your mail host

MDaemon has no fixed address. Your mail host is your own server name, the base of your Webmail address without the :3000 on the end, like mail.yourdomain.com.

Where: the address bar of MDaemon Webmail, minus the port, then your admin if unsure

2. POP or IMAP must be on for the account

MDaemon turns POP and IMAP on or off for each account one by one. If a mailbox cannot connect, its IMAP or POP access may be unticked.

Where: Enable POP and IMAP below →

About MDaemon#

MDaemon is a Windows email server from MDaemon Technologies, once known as Alt-N, that businesses run on their own machine.

Because MDaemon is self-hosted, no single server address fits everyone. Your mail host is your own server name. What trips people up is that MDaemon runs two web pages on their own ports: Webmail, once called WorldClient, on port 3000, and Remote Administration on port 1000. Those are web addresses for reading mail and managing the server, so neither goes in an email app. Your client uses the standard ports 993, 995, 465 and 587. MDaemon also ships with AutoDiscover on by default, so a client may find those settings from your email address alone when the admin has added the matching DNS record.

Service NameMDaemon Email Server
Owned ByMDaemon Technologies (ex Alt-N)
TypeSelf-hosted Windows mail server
Server HostYour own domain, like mail.yourdomain.com
WebmailMDaemon Webmail, port 3000
ProtocolsIMAP, POP3, SMTP, ActiveSync
App PasswordOnly if two factor is on in Webmail
Max Message SizeSet by admin
Every MDaemon uses the same ports: only the host changes from one server to the next. Only your host is unique, while 993, 995, 465 and 587 hold constant. Not sure of your host? It is the base of your Webmail address without the :3000.

MDaemon Access Login#

You can always read your mail in a browser through MDaemon Webmail. The key addresses are:

Webmail

mail.yourdomain.com:3000

Remote Administration

mail.yourdomain.com:1000

Change Password

Webmail → Options or ask your admin

Port 3000 and port 1000 are web pages, not mail settings. Webmail on 3000 reads mail in a browser. Remote Administration on 1000 manages the server. Never type either into Outlook or a phone. Mail apps only use the host and ports in the tables below.

Enable POP and IMAP#

MDaemon decides POP and IMAP access one account at a time, not once for the whole server. If a mailbox will not connect, its access is likely unticked. This is a job for an admin, so skip ahead if IMAP already works for you.

  1. Open Remote Administration at mail.yourdomain.com:1000, or the MDaemon console on the server, then sign in as an administrator.
  2. Open the account under Accounts, then go to its Mail Services screen.
  3. Tick Enable POP access and Enable IMAP access as needed. Save the account.
  4. Confirm the SSL ports are on. Under Security, SSL and TLS, the dedicated ports 993, 995 and 465 should be enabled for the server.
MDaemon Mail Services checkboxes per account Account → Mail Services Enable POP access Enable IMAP access MultiPOP and MDaemon Connector (optional) Ticked here, the mailbox accepts a mail client
Access is per mailbox. One account can allow IMAP while another does not.

MDaemon IMAP Settings#

IMAP is the incoming protocol most people should use. It keeps your mail on the server so every device shows the same inbox.

IMAP ServerYour MDaemon host, like mail.yourdomain.com
Port993 (SSL) or 143 (STARTTLS)
EncryptionSSL/TLS or STARTTLS
UsernameYour full email address on your domain
PasswordYour MDaemon account password
AuthenticationRequired

MDaemon POP3 Settings#

POP3 downloads mail to 1 device. Pick it only if you want a local copy on a single computer. Not sure? See the comparison below.

POP3 ServerYour MDaemon host, like mail.yourdomain.com
Port995
EncryptionSSL/TLS (required)
UsernameYour full email address
PasswordYour MDaemon account password
POP3 empties the server unless you tell it not to. POP suits one computer. Turn on "leave a copy on the server" so mail still shows in MDaemon Webmail or choose IMAP to keep every device matched.

MDaemon SMTP Settings#

Send on 465 or 587, not the web ports: use SMTP 465 with SSL or 587, the MDaemon submission port that always requires authentication. Turn login on for outgoing mail. The web ports 3000 and 1000 are never used for sending.

SMTP handles outgoing mail. When mail comes in but will not go out, this section is where to look.

SMTP ServerYour MDaemon host, like mail.yourdomain.com
Port (SSL)465
Port (STARTTLS)587
EncryptionSSL or STARTTLS (required)
UsernameYour full email address
PasswordSame account password as incoming
AuthenticationRequired. Check "My outgoing server requires authentication" in Outlook.

Check MDaemon IMAP Settings Online#

You don't need to download anything to check MDaemon IMAP settings. The ports here are verified and copy straight from your browser. Since MDaemon runs on your own domain, the host belongs to you, so the checker below points known consumer domains to their own guides. For your MDaemon domain, use the host from the tables with the ports above.

Your Webmail address minus 3000 is your mail host Webmail address, drop the :3000 Use as your IMAP host Use as your SMTP host
The port 3000 belongs to Webmail. Your mail host is the plain name without it.

Does my email address use these settings?

Runs in your browser only. Your address is never sent anywhere or stored.

Want to test the account before setting up an app? Sign in to MDaemon Webmail on port 3000, which proves your address and password work. When that loads, any mail app connects with the values from the tables above.

Look Up IMAP Settings for Any Email Domain#

This page covers MDaemon. For every other address, work email on a company domain included, we run a free online lookup database: imapsettings.com.

imapsettings.com

Enter any email address and get the incoming and outgoing server settings for that domain in 1 step:

Incoming server: hostname, port, SSL/TLS and username format
Outgoing server: SMTP hostname, port and encryption

Your address is used only to find the settings for that domain. Nothing is stored or shared.

Your Password and Sign In#

On most MDaemon accounts you sign in with your normal account password. An app password comes into play only when two factor is switched on for that account in Webmail.

Which password to use in mail apps Two factor offUse your account password Two factor onUse an app password
Most accounts fall on the left. Only make an app password when two factor is on.
Where you sign inAccount passwordApp password
MDaemon Webmail✓ Works✗ Not used
Outlook, Apple Mail, Thunderbird (no 2FA)✓ Works✗ Not needed
Phone mail apps (no 2FA)✓ Works✗ Not needed
Any mail app once two factor is on✗ Fails✓ Required

Make an App Password (only with two factor)

  1. Sign in to MDaemon Webmail on port 3000 and open Options.
  2. Find the two factor area. App passwords only appear once two factor is on for the account.
  3. Create an app password and label it after the app, for example Outlook or iPhone Mail.
  4. Copy the code and paste it into that app in place of your normal password.
  5. No two factor on the account? Skip all of this and sign in with your usual account password.
Good to know: most MDaemon accounts never need an app password. If a client is refused, first check POP or IMAP is ticked for that account, then that you typed the mail host, not the 3000 or 1000 web address.

Set Up MDaemon in Email Clients#

Put your MDaemon mail host in for both incoming and outgoing, with IMAP 993 and SMTP 465. On phones you can add the account as Exchange when the ActiveSync add on is licensed, which pulls mail, calendar and contacts.

MDaemon account setup at a glance What to enter in any mail app Incoming (IMAP) Server: your MDaemon host Port: 993 Security: SSL/TLS Outgoing (SMTP) Server: your MDaemon host Port: 465 Security: SSL/TLS Username: your full email address Password: your account password, or app password if two factor is on
One host serves both incoming and outgoing. Only the port changes.

The mail settings here cover IMAP. For calendar and contacts on a phone, the ActiveSync add on covers it.
Try AutoDiscover first. MDaemon turns on AutoDiscover by default. If your admin created the autodiscover DNS record for your domain, Outlook and phone Exchange setup can pull the host, ports and encryption from your email address and password alone. When it does not fill in, enter the values by hand as shown below.
How MDaemon AutoDiscover fills in settings Enter email addressand password autodiscover DNS recordset up for your domain? Yes No Client fills host and ports itself Enter the host and ports by hand
With the DNS record in place, setup needs only your address and password. Without it, use the tables here.

Jump to your app:

Outlook (Windows and Mac)

  1. Open Outlook → File → Add Account (in new Outlook, Settings → Accounts → Add account).
  2. Enter your MDaemon address, open Advanced options and check "Let me set up my account manually".
  3. Choose IMAP and set your mail host to 993 with SSL incoming and the same host to 465 with SSL outgoing.
  4. Enter your account password. Switch on "outgoing server requires authentication".
  5. Need shared calendars and contacts? The MDaemon Connector adds them to Outlook the way an Exchange account would.

Apple Mail (macOS)

  1. Open Mail → Settings → Accounts → Add Account → Other Mail Account.
  2. Enter your name, MDaemon address and account password, then continue.
  3. When detection fails, set your MDaemon mail host as both incoming and outgoing.
  4. Set IMAP to 993 SSL incoming and 465 SSL outgoing, using your full address as the username.
  5. Enable Mail in the checkbox list and finish. Accept the certificate if it prompts.

iPhone and iPad

  1. For mail only, open Settings → Apps → Mail → Mail Accounts → Add Account → Other, then Add Mail Account.
  2. Enter your name, MDaemon address and account password, keep IMAP selected.
  3. Set your MDaemon mail host for incoming and outgoing, 993 SSL and 465 SSL.
  4. For mail, calendar and contacts, add the account as Exchange when ActiveSync is licensed, using your host as the server.
  5. Tap Save and wait for iOS to verify the account.

Android

  1. Open your mail app (Gmail app, Samsung Email or another) → Add account.
  2. Choose Other or IMAP, or Exchange when ActiveSync is licensed for mail, calendar and contacts.
  3. Type your address and account password, then open Manual setup for IMAP.
  4. Enter the servers: your MDaemon host 993 SSL incoming, the same host 465 SSL outgoing.
  5. Finish setup and pull down to sync your inbox.

Thunderbird

  1. Open Thunderbird → Account Settings → Account Actions → Add Mail Account.
  2. Enter your name, MDaemon address and account password, then select Continue.
  3. Choose Configure manually, because Thunderbird cannot guess a private host.
  4. Point both servers at your MDaemon host, IMAP 993 SSL and SMTP 465 SSL, with your full address.
  5. Select Done. Folders sync on first open.

MDaemon Webmail Settings#

Server settings connect your apps. These control how your MDaemon mail behaves. All of them live in MDaemon Webmail on port 3000, under Options.

Signature

Options, then Compose. A signature made here shows in Webmail only. Outlook and other apps keep their own.

Vacation Auto Reply

Options, then Autoresponder. Set start and end dates so it stops on its own. The reply goes out even with your computer off because the MDaemon server sends it.

Filters and Folders

Options, then Filters. Rules here run on the MDaemon server, so they sort mail before your phone or Outlook sees it. Rules that live in an app only fire while that app is open.

Spam and Blocked Senders

Options, then Spam. Flag a message as spam and manage your allowed and blocked senders. The main spam filter is tuned by your admin on the server.

POP3 vs IMAP#

FeatureIMAPPOP3
Where mail livesOn the MDaemon serverDownloaded to 1 device
Multiple devices✅ Everything stays in sync❌ Each device sees different mail
Sent and deleted mail✅ Synced everywhere⚠️ Stays only on that device
Offline reading⚠️ Cached mail only✅ Full local copy
Server storage usedYes, counts against your quotaCan be freed after download
Best forPhone + computer, everyday useSingle PC, local archives
Our verdict: use IMAP on computers and ActiveSync on phones, since both keep the server and your devices matched. Save POP for one lone machine. For a lasting offline copy, a backup tool beats POP3 at that job.

MDaemon Sending and Storage Limits#

On MDaemon the limits belong to your admin, not a fixed policy. These are the settings that decide what goes through, each tuned in the server console or Remote Administration:

Max message sizeSet in the server or per domain
Recipients per messageAdmin controlled
Mailbox quotaSet per account or domain
AttachmentsCounted inside the message size limit
Which protocols are openPOP and IMAP ticked per account
What happens at the limitOversized mail is refused, a full mailbox bounces new mail

Troubleshooting MDaemon Connections#

Find the exact error your email app shows, then apply the fix:

Error you seeWhat it meansFix
Authentication failed Wrong password or two factor is on Retype the account password. If two factor is on for the account, use an app password from Webmail.
Cannot connect on port 3000 or 1000 Those are web pages, not mail ports Use your mail host with 993 for IMAP and 465 or 587 for SMTP. Port 3000 is Webmail, 1000 is Remote Administration.
IMAP access is disabled POP or IMAP is unticked for that account Ask an admin to tick IMAP access on the account Mail Services screen.
550 relaying denied Outgoing mail is not authenticating Turn on "outgoing server requires authentication" and send on 465 or 587. Port 587 always needs a login.
Messages stuck in Outbox SMTP authentication is off Enable "outgoing server requires authentication" with the same login as incoming mail.

Reader Reported Fixes

Two fixes that come up over and over in MDaemon setups, beyond the error table above.

Use the mail host, not the :3000 or :1000 address. The mail host is the plain server name. The 3000 address is Webmail and the 1000 address is Remote Administration. Pasting a web address into a mail app is the most common MDaemon mistake.

Check the account before blaming the client. MDaemon can allow IMAP on one mailbox and block it on the next. If a single account cannot connect while others can, open its Mail Services screen and tick the access it needs.

Handling an MDaemon certificate warning Certificate warning Your own server: accept once Install Let's Encrypt: no warnings
A warning on a self-signed certificate is expected. A real certificate clears it for good.

Moving Mail to or from MDaemon?#

Moving to a new MDaemon server? The Univik Email Migration Tool moves every folder over IMAP in one run. Put the old host on one side and your new MDaemon host on the other, each with a full address and account password.

Leaving MDaemon for Microsoft 365 or Google? The same tool reads your MDaemon mailbox folder by folder with the settings on this page and writes it into the new account.

Coming to MDaemon from another provider? Enter your old account on one side and your MDaemon host on the other. Every folder and date stays intact.

Back up before any big change. Save the mailbox first so you hold a copy whatever happens during the move.

Rather not do it yourself? Our Email Migration Services team plans and runs the whole transfer for you and verifies every folder arrived.

Use These Settings in Univik Email Backup#

The same IMAP settings above let you download your complete MDaemon mailbox to your computer. Univik Email Backup saves everything as PST, MBOX, EML or PDF files you keep forever, even if the server is retired.

  1. Download Univik Email Backup and install it on Windows.
  2. Select IMAP from the source list. MDaemon is not named, so IMAP is the option to pick.
  3. Sign in with your full email address and your app password. Your regular password won't work here either.
  4. If the tool asks for server details, use your MDaemon host with port 993 and SSL from the IMAP table above.
  5. Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Why back up before switching providers: POP3 grabs only the inbox while a closed account bounces every reply. A full IMAP backup keeps every folder, attachment and date stamp in files any email app can open later. Moving to a new account instead of archiving? Use the email migration tool to move mail straight between accounts.

Email Settings Glossary#

IMAP

Internet Message Access Protocol. Keeps mail on the server, so every device sees one inbox with the same folders and read marks.

POP3

Post Office Protocol version 3. Downloads mail to 1 device and can remove it from the server. An older method that still suits local archives.

SMTP

Simple Mail Transfer Protocol. Sends your outgoing mail. It works alongside IMAP or POP3, which only pull mail in.

SSL / TLS / STARTTLS

Encryption for the connection. SSL/TLS encrypts from the start (ports 993, 995, 465). STARTTLS upgrades a plain connection (port 587).

App Password

A 16 character code that replaces your real password inside email apps. Safer because you can revoke 1 app without changing your main password.

OAuth

Sign in through the provider's own window instead of typing a password into the app. The modern method most providers are moving to.

How We Verify These Settings#

Univik builds email backup, migration and converter software since 2013. Our tools sign in to MDaemon servers over IMAP and SMTP every day for thousands of users, so a port, access or login quirk shows in our connection logs before most guides catch it.

Every value here is confirmed with 3 checks: live IMAP and SMTP connections from Univik Email Backup, a comparison against the MDaemon Technologies documentation, then a test sign in from a mail client. We re verify after any MDaemon release and at least once a quarter.

Frequently Asked Questions

The mail server is your own MDaemon host, like mail.yourdomain.com. IMAP uses port 993 with SSL. For sending, use port 465 with SSL or 587 with STARTTLS. Sign in with your full email address and your MDaemon account password.

Common causes, in the order to check them: POP or IMAP is unticked for that account. The client points at the 3000 or 1000 web address instead of the mail host. Two factor is on so you need an app password.

Use IMAP on a computer and ActiveSync on a phone. Both keep the MDaemon server and your devices matched. POP3 suits a lone computer where you want a local download. Full comparison here.

It is your own server name, the base of your Webmail address without the :3000 on the end, like mail.yourdomain.com. Use that host for incoming and outgoing. The 3000 and 1000 web addresses never go in a mail app. If your admin set up AutoDiscover, a client can often fill the host in for you from your email address.

Only if two factor is on for the account in Webmail. Without it, your normal MDaemon account password works everywhere. With it, you make an app password in Webmail and use that in mail apps.

Port 3000 is MDaemon Webmail, once called WorldClient, opened at mail.yourdomain.com:3000 in a browser. Port 1000 is Remote Administration. Both are web pages, so neither goes in a mail app. Clients use 993, 995, 465 or 587.

An IMAP client saves mail as it syncs, though a dedicated backup tool is quicker and writes standard files you can open anywhere. See how to back up your MDaemon mailbox. Doing it before you move or rebuild a server means you hold your own copy.

Yes. IMAP carries mail only. For calendar, contacts and tasks, MDaemon offers its ActiveSync add on for phones and the MDaemon Connector for Outlook. Other apps can use CalDAV and CardDAV against the same server.

An email migration tool moves mail straight between the 2 accounts over IMAP. You need your MDaemon host and account password for this side, plus the destination account details. Every folder and date stays intact.

If setting this up feels risky or you have many accounts to move, our managed email migration service does the entire job for you.
