Username Your full email address

Quick answer: SingNet email runs on MyPortal. Every protocol connects to imap.singnet.com.sg. IMAP is on 993, POP3 on 995 and SMTP on 465, each secured with SSL. Your username is the full address and the mailbox password you set in MyPortal lets you in. Your exact values also sit under your SingNet mail settings in MyPortal. Cannot log into My Account? SingNet email and OnePass split.

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#

A host changes how you sign in more often than it changes the server names. Here is the current status for SingNet and what it means for your setup.

Worth knowing

Use the full singnet.com.sg address. SingNet turns down a bare mailbox name. Put you@singnet.com.sg on both incoming and outgoing.

Worth knowing

Two servers, both secured. Read mail from imap.singnet.com.sg on 993. Send through smtp.singnet.com.sg on 465. Both need SSL and a sign-in.

Worth knowing

The old plain ports stopped working. Singtel requires SSL on both servers now. It blocks port 25, so a setup on 25 or 110 fails.

Current status: incoming mail uses imap.singnet.com.sg on 993 with SSL. Outgoing uses smtp.singnet.com.sg on 465 with SSL. Your User ID is the full singnet.com.sg address and both servers need the sign-in.

Before You Begin#

Handle these two basics before anything else. Skip them and your email app will reject the connection even when every server value is correct.

1. Create the mailbox

Add the address under your mail settings in MyPortal and set its password. That password is the one your apps use.

Where: MyPortal then your mail settings

2. Open your SingNet mail settings

Click MyPortal next to the address, then your SingNet mail settings to read the server name and secure ports.

About SingNet Mail#

SingNet Mail is the email service of Singtel, Singapore's largest telecom provider. Singtel moved SingNet to a secured setup, so the settings now insist on SSL and a sign-in on both servers.

Incoming mail uses imap.singnet.com.sg on port 993 with SSL. Outgoing mail uses smtp.singnet.com.sg on port 465 with SSL. Your User ID and password are required on both. The old plain path on port 25 or 110 no longer works. During the security upgrade Singtel also asked members to reset the SingNet password.

Service NameSingNet Mail
Run BySingtel, Singapore
Address Domainsingnet.com.sg
Incoming Serverimap.singnet.com.sg, port 993, SSL
Outgoing Serversmtp.singnet.com.sg, port 465, SSL
Sign-inUser ID and password, both servers
UsernameFull singnet.com.sg address
Member siteMyPortal
SSL is required: both servers need an SSL connection now. If an app was set up years ago on a plain port, that is the usual reason it stopped connecting.

SingNet Webmail Login#

You can always read your mail in a browser. The official sign in pages are:

SingNet Mail Guide

singtel.com/support

Watch out for fake support pages. Many pages ranking for email settings show a phone number and ask you to call for "expert setup help". SingNet and Univik never ask you to call a number to enter server settings. Everything you need is free on this page.

Find Your Settings#

IMAP is ready the moment a mailbox exists, so nothing needs switching on. To read the exact values for one address, SingNet lists them inside MyPortal.

  1. Log in to MyPortal from your SingNet client area.
  2. Open your mail settings in the Email section.
  3. Click MyPortal beside your address, then your SingNet mail settings.
  4. Pick your app or read the manual settings for the server name and secure ports.
Server name or imap.singnet.com.sg? Both reach the same mailbox. For a clean SSL connection use the server hostname from that screen, since it matches the certificate before your own domain SSL is in place.

SingNet IMAP Settings#

IMAP is the incoming choice SingNet points most people to. Mail stays put on the server, so a laptop and a phone read one shared inbox. Pull the exact server name from your SingNet mail settings in MyPortal.

IMAP Serverimap.singnet.com.sg
Port993
EncryptionSSL/TLS (required)
UsernameYour full email address, including @singnet.com.sg
PasswordYour mailbox password
AuthenticationRequired

SingNet's Secured Setup Uses IMAP#

Singtel's current guide for SingNet is the secured IMAP setup. It points to imap.singnet.com.sg on 993 with SSL for incoming mail, which keeps your mail on the SingNet server and shows the same inbox on every device. Enter that rather than an old POP server on port 110.

Secured setup: use imap.singnet.com.sg on port 993 with SSL for incoming mail. Outgoing goes through smtp.singnet.com.sg on 465 with SSL. Both need your User ID and password.

SingNet SMTP Settings#

Stay on the secure ports: SingNet lists 993 for IMAP and 995 for POP3 over SSL. The plain ports 143 and 110 exist but send your login unencrypted, so keep SSL set.

SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.

SMTP Serversmtp.singnet.com.sg
Port (SSL)465
Port (STARTTLS)587
EncryptionSSL or STARTTLS (required)
UsernameYour full email address
PasswordSame as incoming mail
AuthenticationRequired. Switch on outgoing server authentication in the client.
Nothing sending? Put sending on 465 with SSL. Many home connections block port 25. SingNet also supports 587 and 26 if 465 is blocked. Confirm outgoing authentication is on.
Name warning? Swap smtp.singnet.com.sg for the server hostname from your SingNet mail settings. That host matches the certificate, so the alert clears.

Check SingNet IMAP Settings Online#

You don't need to download anything to check SingNet IMAP settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address uses SingNet servers? Type it below and find out instantly.

Does my email address use these settings?

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

Want to verify the account itself before configuring an app? Sign in at SingNet webmail, which confirms your address and password work, then confirm an SingNet email password exists. If both pass, any email app connects with the tables above.

Look Up IMAP Settings for Any Email Domain#

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

imapsettings.com

Complete email settings database, by Univik

Check IMAP settings online →

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.

Username and Password#

Both come from the mailbox itself. The username is the whole email address and the password is the one you chose when you built the address in MyPortal. A standard SingNet mailbox uses no SingNet email password.

Username is the full address

Type you@singnet.com.sg in full, with the part after the at sign. SingNet turns down a bare mailbox name.

Put that same address on both incoming and outgoing.

Password is the mailbox one

This is the webmail password you set under your mail settings in MyPortal, not your SingNet client area login. Reset it there if an app keeps refusing it.

The two factor prompt in the SingNet client area guards billing, not the mailbox connection.

Forgot the password? Head to your mail settings in MyPortal, locate the address, click Manage and enter a new password. Change it in each app after that.

Set Up SingNet in Email Clients#

The servers and ports are always the same. Only the menus differ. Jump to your app:

Outlook (Windows and Mac)

  1. In Outlook select Add Account, then turn on manual setup under Advanced options.
  2. Choose IMAP and set incoming to imap.singnet.com.sg on 993 with SSL.
  3. Set outgoing to the same server on 465 with SSL.
  4. Enter the full address and mailbox password when Outlook prompts you.
  5. Send a test message to yourself to prove both paths.

Apple Mail (macOS)

  1. In Mail select Add Account, then pick Other Mail Account.
  2. Give your name, SingNet address and password, then continue.
  3. Enter imap.singnet.com.sg with SSL on incoming and outgoing.
  4. Keep the SSL ports so nothing sends in plain text.
  5. Save and wait for the mailbox to load.

iPhone and iPad

  1. In Settings open Mail, then tap Mail Accounts and Add Account.
  2. Tap Other then Add Mail Account and fill your details.
  3. Keep IMAP chosen and put imap.singnet.com.sg in both server boxes.
  4. Leave the secure ports iOS fills, since SingNet expects SSL.
  5. Tap Save and let iOS run its check.

Android

  1. Open your mail app and tap Add account, then Other or IMAP.
  2. Put in your address and password. Switch to manual setup if it stalls.
  3. For incoming use imap.singnet.com.sg on 993 over SSL.
  4. For outgoing use smtp.singnet.com.sg on 465 over SSL.
  5. Save and swipe down to fetch your mail.

Thunderbird

  1. In Thunderbird pick Account Actions, then Add Mail Account.
  2. Type your name, SingNet address and password, then Continue.
  3. Wait for detection, then make sure IMAP with SSL is picked.
  4. If detection fails, type imap.singnet.com.sg in yourself.
  5. Hit Done and the folders fill in on the first sync.

SingNet Webmail Settings#

Server settings connect your apps. The controls here shape how the mailbox acts on its own. They live in a mail app set up with the singnet.com.sg address over secured IMAP.

Signature

Add one in the webmail preferences. It rides on mail sent from webmail. A desktop app keeps a signature of its own.

Vacation Auto Reply

Set an autoresponder in MyPortal and give it start and end dates. The SingNet server delivers it, so it fires even when your machine is off.

Filters and Folders

Create filters from the SingNet webmail filters in MyPortal. A server side rule sorts a message ahead of any device fetching it. A rule set inside an app only works while that app is running.

Spam and Blocked Senders

SingNet runs SpamAssassin on incoming mail. Set the threshold and block unwanted senders in MyPortal. Flagged mail lands in the junk folder for a look.

POP3 vs IMAP#

FeatureIMAPPOP3
Where mail livesOn the SingNet 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

Best forPhone + computer, everyday useSingle PC, local archives
Our verdict: pick IMAP unless you have a clear reason not to. If you want a permanent offline archive of your SingNet mailbox, a backup tool does that job better than POP3.

SingNet Mail at a Glance#

Troubleshooting SingNet Connections#

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

Error you seeWhat it meansFix
Username or password rejected Short username or wrong password Use the full email address with the mailbox password from MyPortal, not the client area login.
Cannot send on port 25 ISP blocks the default SMTP port Switch outgoing to 465 with SSL. SingNet also accepts 587 and 26 if 465 is blocked.
My old setup stopped connecting It was on a plain, unsecured port Singtel moved SingNet to a secured setup. Change incoming to imap.singnet.com.sg on 993 with SSL and outgoing to smtp.singnet.com.sg on 465 with SSL. A plain setup on 25 or 110 no longer works.
Password is rejected after the security upgrade The SingNet password needs a reset Singtel asked members to reset the SingNet password during the security upgrade. Set a new one, then use the full singnet.com.sg address with it on both servers.
Cannot connect to server Wrong port or encryption Set 993 with SSL incoming and 465 with SSL outgoing. A firewall on your own machine can block it as well.
Repeated password prompt Short username or a typo Clear the saved login, then put in the full address with the mailbox password.
Messages stuck in Outbox SMTP authentication is off Enable "outgoing server requires authentication" with the same login as incoming mail.
My SingNet email will not log into My Account or OnePass SingNet email is no longer a OnePass login After the refresh, SingNet email cannot sign into OnePass. Use an alternative email, a mobile number on your OnePass account or SingPass if you are the main holder. Your SingNet ID still works at MyPortal for mail.
The SingNet portal asks for a mobile number I did not set Multi-factor sign-in is now required The SingNet Email portal added multi-factor sign-in, so a valid mobile number is now mandatory for the one-time code. Add one in the portal, even if you already take the code by an alternative email.

Reader Reported Fixes

Copy from your SingNet mail settings. When a manual setup will not connect, the your SingNet mail settings page in MyPortal prints the exact server name and ports for that mailbox. Pasting those in clears the guesswork behind most failed setups.

Test the login in webmail first. Sign in at webimap.singnet.com.sg with the full address and mailbox password. If webmail works, the credentials are right and the issue sits in the app settings.

SingNet Email and Singtel OnePass Split Apart #

Singtel OnePass is the single login for managing Singtel services in My Account and the My Singtel app. After the security refresh, a SingNet email address can no longer sign into OnePass. That link is gone. To reach OnePass now, use an alternative email, a mobile number tied to the account or SingPass if you are the main account holder.

For the mail itself, nothing is lost. You still sign in at MyPortal with your SingNet email ID to read and manage mail. The split is only about identity. SingNet email is for mail, while OnePass is for the account and billing side.

Two housekeeping steps came with the refresh. Singtel asked for a one-time password reset, so the SingNet credentials match the new policies. Use that new password everywhere the SingNet address signs in. The SingNet Email portal also added multi-factor sign-in, so a valid mobile number is now required for the one-time code, even if you take the code by alternative email.

PointWhat to know

Moving Mail In or Out?#

SingNet mail speaks plain IMAP, so a mailbox moves in or out like any SingNet account. Each folder stays on the server until the move finishes.

Take a copy first. Back up the mailbox before a move. A note that arrives mid switch can sit on either side. A copy keeps you safe.

Carrying mail across? The Univik Email Migration Tool moves each folder over an IMAP link. Give it the SingNet server name and mailbox password on this side and the other account opposite.

Rather hand it off? Our Email Migration Services team runs the whole move and verifies each folder arrived.

Use These Settings in Univik Email Backup#

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

  1. Download Univik Email Backup and install it on Windows.
  2. Select SingNet from the source list. If it isn't listed by name, choose IMAP.
  3. Give the complete email address with your mailbox password. The login name is always the whole email address.
  4. When the backup tool wants server details, hand it imap.singnet.com.sg on port 993 with SSL for SingNet. Take those values straight from the IMAP table above, with port 993 over SSL.
  5. Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Why back up before switching providers: POP3 only grabs the inbox and vacation replies to a closed account bounce. 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 copy mail directly between accounts.

Email Settings Glossary#

IMAP

Internet Message Access Protocol. Reads mail that stays on the SingNet server, so every device shows the same inbox. Use imap.singnet.com.sg on port 993 with SSL.

SMTP

Simple Mail Transfer Protocol. Sends your outgoing mail through smtp.singnet.com.sg on port 465 with SSL. Your User ID and password are required to send.

SSL

The encryption SingNet now requires on both servers. Incoming uses it on 993 and outgoing uses it on 465. A plain connection is refused.

imap.singnet.com.sg

The incoming server for a SingNet address. Set it on port 993 with SSL to read your SingNet inbox.

smtp.singnet.com.sg

The outgoing server for a SingNet address. Set it on port 465 with SSL to send from your SingNet address.

singnet.com.sg

The SingNet mail domain. Your address looks like yourusername@singnet.com.sg. The whole address is your login.

SingNet

The internet and mail brand of Singtel, Singapore's largest telecom provider. SingNet Mail is its email service.

Singtel

Singapore Telecommunications, the parent behind SingNet. Its support pages hold the current SingNet mail guide.

User ID

Your SingNet login for the mail servers. It is the full singnet.com.sg address, needed on both incoming and outgoing.

SingNet Password

The password for the mailbox. Singtel asked members to reset it during a security upgrade, so an old one can be out of date.

MyPortal

The SingNet member site where you sign in with your SingNet email ID to manage mail and account details.

Port 25

The old plain sending port. Singtel blocks it to cut spam, so outgoing mail uses 465 with SSL instead.

Singtel OnePass

The single Singtel login for My Account and the My Singtel app. A SingNet email address no longer signs into it.

Account Refresh

Singtel's security exercise that split SingNet email from OnePass and asked for a password reset. A one-time step.

Multi-Factor Sign-In

A second check at login. The SingNet Email portal now sends a one-time code, so a valid mobile number is required.

How We Verify These Settings#

Univik builds email backup, migration and converter software since 2013. Our tools sign in to SingNet over IMAP and SMTP every day for thousands of users, so a changed server, port or login rule shows up in our connection logs before most guides notice it.

Every value on this page is confirmed with three checks: a live IMAP and SMTP connection from Univik Email Backup, a comparison against the SingNet guides and a sign in with a real mailbox using the full address. We re verify after any provider announcement and at least once a quarter.

Found something that no longer matches what SingNet shows you? Tell us and we will retest and update the page, with the change logged in what changed recently.

Frequently Asked Questions

For incoming mail use imap.singnet.com.sg on port 993 with SSL. For outgoing use smtp.singnet.com.sg on port 465 with SSL. The username is your full singnet.com.sg address. Your User ID and password are required on both.

Singtel moved SingNet to a secured setup, so SSL is required on both servers. An app set up years ago on a plain port fails. Use imap.singnet.com.sg on 993 and smtp.singnet.com.sg on 465, each with SSL.

Singtel's current guide is the secured IMAP setup. It keeps mail on the SingNet server, so every device shows the same inbox, on imap.singnet.com.sg over 993. Enter that rather than an old POP server on port 110.

Yes. The server names and ports are identical everywhere. You enter imap.singnet.com.sg for incoming and smtp.singnet.com.sg for outgoing. Only the menu wording differs between apps.

Singtel ran a security upgrade and migrated SingNet email credentials to new policies. That is why a reset was needed. Set a new password, then use the full singnet.com.sg address with it on both servers.

Yes. The secured setup is built for exactly this. Both servers use SSL, incoming on 993 and outgoing on 465. Each checks your User ID and password. That is more secure than the old plain ports.

Add the account over IMAP so the folders sync, then let the app finish downloading. In Thunderbird or Outlook you can then export a folder to a local file. IMAP leaves the originals on the SingNet server while you copy.

Two changes explain most cases. SingNet now requires SSL, so a plain setup fails. The security upgrade also asked for a password reset. Move to imap.singnet.com.sg on 993 and smtp.singnet.com.sg on 465 with SSL, then set the new password.

At MyPortal, on the Singtel support site. Sign in with your SingNet email ID to look after mail and account details. Singtel's SingNet guide there has the current server values as well.

Because the security refresh split the two. A SingNet email address no longer signs into Singtel OnePass. For OnePass, use an alternative email, a mobile number on the account or SingPass if you are the main holder. Your SingNet email ID still works at MyPortal for reading mail. The refresh also asked for a one-time password reset. The SingNet portal now needs a mobile number for its security code. The section above has the detail.
