Quick answer: DNA uses two server names. Incoming is mail.dnamail.fi, on 993 for IMAP or 995 for POP3. Outgoing is smtp.dnamail.fi on 465. Each connects over SSL. Sign in with your full address and your DNA mailbox password. On an old Welho or dnainternet.net name? Switch to these. DNA Mail also leaves out a few features. See what.
What Changed Recently#
DNA merged its DNA and Welho mail onto one platform in late 2024. Here is the current status and what a DNA address needs now.
Worth knowing
DNA and Welho share one platform now. Since November 2024 the recommended host is dnamail.fi. The old welho.com and dnainternet.net names still work.
Worth knowing
Incoming and outgoing use different names. Reading mail uses mail.dnamail.fi. Sending uses smtp.dnamail.fi. Both connect over SSL with your full address as the username.
Worth knowing
DNA email is for existing accounts only. DNA no longer opens new mailboxes. An existing address keeps working, though new users are pointed to Gmail or Outlook.
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. An existing DNA address
Your address is you@dnainternet.net or a welho.com one. The password is your DNA mailbox password, reset in webmail.dna.fi.
Where: webmail.dna.fi
2. The recommended names
Read mail on mail.dnamail.fi and send on smtp.dnamail.fi. The old welho.com and dnainternet.net names still connect too.

About DNA Mail#
DNA is one of Finland three large telecoms, alongside Elisa and Telia. It runs the DNA email service and absorbed the Welho cable brand.
DNA is a Finnish operator that took over the Welho cable network and its email. The point to remember is that DNA now uses two server names, mail.dnamail.fi for reading and smtp.dnamail.fi for sending. You log in with the whole address and your DNA mailbox password.
| Service Name | DNA Email |
| Email Domains | dnainternet.net, welho.com |
| Provider | DNA (Finland) |
| Incoming Host | mail.dnamail.fi |
| Outgoing Host | smtp.dnamail.fi |
| Email Type | dnainternet.net or welho.com, such as you@dnainternet.net |
| Webmail | webmail.dna.fi |
| New Accounts | Existing customers only |
| Protocols Supported | IMAP, POP3, SMTP |
| App Password Needed | No, mailbox password |
| Username | Full email address |
DNA Webmail Login#
You can always read your mail in a browser. The official sign in pages are:
Find Your Settings#
IMAP is ready on an existing DNA mailbox. Reading uses mail.dnamail.fi and sending uses smtp.dnamail.fi. Here are the exact values.
- Open your email app and add a new account.
- Set incoming to mail.dnamail.fi on 993 with SSL.
- Set outgoing to smtp.dnamail.fi on 465 with SSL.
- Use your full address as the username, with SMTP authentication on.
DNA IMAP Settings#
IMAP is the incoming choice DNA points most people to. Mail stays put on the server, so a laptop and a phone read one shared inbox. The incoming host is mail.dnamail.fi over 993.
| IMAP Server | mail.dnamail.fi | |
| Port | 993 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full address, including the part after the at sign | |
| Password | Your mailbox password | |
| Authentication | Required |
DNA 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 Server | mail.dnamail.fi | |
| Port | 995 | |
| Encryption | SSL/TLS (required) | |
| Username | Your full email address | |
| Password | Your mailbox password |
DNA SMTP Settings#
SMTP handles outgoing mail. If you can read mail but not send it, the problem is here.
| SMTP Server | smtp.dnamail.fi | |
| Port (SSL) | 465 | |
| Port (STARTTLS) | 587 | |
| Encryption | SSL on 465 or STARTTLS on 587 | |
| Username | Your full DNA address | |
| Password | Your DNA mailbox password | |
| Authentication | Required off the DNA network. Turn on outgoing authentication with your address and password. |
465 with SSL. Many home connections block port 25. DNA also accepts 587 with STARTTLS if 465 is blocked. Confirm outgoing authentication is on, with your full address and password.
Check DNA Settings Online#
You don't need to download anything to check DNA settings online. This page is the lookup: every value is verified, current and copyable straight from your browser. Not sure your address is a DNA one? Type it below to check in a moment.
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 webmail.dna.fi, which confirms your address and password work. If webmail opens, the credentials are right and any email app connects with the tables above.
Look Up IMAP Settings for Any Email Domain#
This page covers DNA. 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
Enter any email address and get the incoming and outgoing server settings for that domain in 1 step:
Your address is used only to find the settings for that domain. Nothing is stored or shared.
Username and Password#
The username is your full DNA address, such as one ending in dnainternet.net or welho.com. The password is your DNA mailbox password, reset in webmail.dna.fi. There is no separate app password.
Username is the full address
Type your full address in, with the part after the at sign. A bare mailbox name is turned down.
Put that same address on both incoming and outgoing.
Password is the mailbox one
This is your DNA mailbox password, reset at webmail.dna.fi. After a reset, DNA asks for a fresh strong authentication. Update every app with the new password.
The strong authentication DNA asks after a password reset guards the account, not each app connection.
Set Up DNA in Email Clients#
The servers and ports are always the same. Only the menus differ. Jump to your app:
Outlook (Windows and Mac)
- In Outlook select Add Account, then turn on manual setup under Advanced options.
- Choose IMAP and set incoming to
mail.dnamail.fion 993 with SSL. - Set outgoing to
smtp.dnamail.fion 465 with SSL. - Enter the full address and mailbox password when Outlook prompts you.
- Send a test message to yourself to prove both paths.
Apple Mail (macOS)
- In Mail select Add Account, then pick Other Mail Account.
- Give your name, DNA address and password, then continue.
- Enter mail.dnamail.fi for incoming and smtp.dnamail.fi for outgoing.
- Keep the SSL ports so nothing sends in plain text.
- Save and wait for the mailbox to load.
iPhone and iPad
- In Settings open Mail, then tap Mail Accounts and Add Account.
- Tap Other then Add Mail Account and fill your details.
- Keep IMAP chosen and put mail.dnamail.fi for incoming with smtp.dnamail.fi for outgoing.
- Leave the secure ports iOS fills, since DNA expects SSL.
- Tap Save and let iOS run its check.
Android
- Open your mail app and tap Add account, then Other or IMAP.
- Put in your address and password. Switch to manual setup if it stalls.
- For incoming use mail.dnamail.fi on 993 over SSL.
- For outgoing use smtp.dnamail.fi on 465 over SSL.
- Save and swipe down to fetch your mail.
Thunderbird
- In Thunderbird pick Account Actions, then Add Mail Account.
- Type your name, DNA address and password, then Continue.
- Wait for detection, then make sure IMAP with SSL is picked.
- If detection fails, type mail.dnamail.fi and smtp.dnamail.fi in yourself.
- Hit Done and the folders fill in on the first sync.
DNA Webmail Settings#
Server settings connect your apps. These controls decide how the mailbox behaves on the server. They live in DNA webmail at webmail.dna.fi, where you sign in with your address and password.
Signature
Add one in the webmail.dna.fi settings under Identities. It rides on mail sent from the browser. A desktop app keeps its own signature.
Vacation Auto Reply
Turn on the holiday reply in webmail.dna.fi under Settings. The server sends it, so it goes out even when your computer is off.
Filters and Folders
Build filters in webmail.dna.fi under Settings. A server side rule sorts a message before any device downloads it. An in app rule only runs while that app is open.
Spam and Blocked Senders
DNA screens incoming mail for spam. Mark unwanted senders in webmail.dna.fi. Flagged mail lands in the junk folder for a look.
POP3 vs IMAP#
| Feature | IMAP | POP3 |
|---|---|---|
| Where mail lives | On the DNA server | Downloaded 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 used | Yes, counts against your quota | Can be freed after download |
| Best for | Phone + computer, everyday use | Single PC, local archives |
DNA Servers at a Glance#
A few details are worth knowing before you set up an app. Here are the DNA server values in one place:
| Incoming host | mail.dnamail.fi (IMAP 993, POP3 995) |
| Outgoing host | smtp.dnamail.fi (SMTP 465 or 587) |
| Encryption | SSL on 465, STARTTLS on 587 |
| Username | Full DNA address |
| Old server names | welho.com, dnainternet.net still work |
| Send limit | 100 messages an hour per account |
Troubleshooting DNA Connections#
Find the exact error your email app shows, then apply the fix:
| Error you see | What it means | Fix |
|---|---|---|
| Username or password rejected | Short username or wrong password | Use your full DNA address with your DNA mailbox password from webmail.dna.fi. A new strong authentication is asked after a reset. |
| Cannot send on port 25 | ISP blocks the default SMTP port | Set outgoing to smtp.dnamail.fi on 465 with SSL. Port 587 with STARTTLS works if 465 is blocked. |
| Old server name warning | Welho or dnainternet.net name | Those older names still connect, though the recommended host is mail.dnamail.fi for incoming and smtp.dnamail.fi for outgoing. |
| Cannot create a new DNA address | Existing accounts only | DNA stopped opening new mailboxes. An existing address keeps working, while new users are pointed to Gmail or Outlook. |
| 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. |
| Forwarding option is missing | DNA Mail has no forwarding | DNA Mail does not forward mail on the server. To copy incoming mail elsewhere, set up forwarding in a full mailbox service such as Gmail or Outlook. You can also pull the mail with a client and a rule. |
| Sending stops after many messages | Hourly send cap reached | DNA allows up to 100 messages an hour and up to 100 recipients a message. Wait for the hour to reset. Then split a large send into smaller batches. |
Reader Reported Fixes
Use the recommended names first. The most common DNA failure is an app still pointing at an old welho.com or dnainternet.net server. Those work, though setting mail.dnamail.fi for incoming and smtp.dnamail.fi for outgoing clears most trouble.
Test the login in webmail first. Sign in at webmail.dna.fi with your address and password. If webmail opens, the credentials are right and the issue is the app settings.
What DNA Mail Leaves Out #
DNA Mail keeps to the basics, so a couple of features you would expect are not there. It has no message forwarding, so you cannot auto-send a copy of incoming mail to another address from the server. It also has no calendar. For either one, a full mailbox service like Gmail or Outlook does more.
Sending has limits that guard the server against spam. One account can send up to 100 messages an hour. A single message can reach up to 100 recipients. Going over either cap pauses your sending for a while, so a large mailout is better split up or handled by a dedicated service.
The address you send from has to be your own DNA address, though a reply can still point somewhere else. The mailbox holds 1 GB. One message with its attachments can reach 25 MB. You can set up to six aliases. Any extra aliases from before the 2024 change keep working, so you only lose the room to add new ones until you drop back under six.
| Feature | DNA Mail |
|---|---|
| Message forwarding | Not available |
| Calendar | Not available |
| Send limit, per hour | Up to 100 messages |
| Recipients, per message | Up to 100 |
| Sending address | Must be your DNA address |
| Reply-To address | Can point elsewhere |
| Mailbox size | 1 GB |
| Message with attachments | Up to 25 MB |
| Aliases | Up to 6 per mailbox |
Moving Mail In or Out?#
DNA mail speaks plain IMAP, so a mailbox moves in or out like any standard account. Each folder stays on the server until the copy 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 mail.dnamail.fi with your address and 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 DNA mailbox to your computer. Univik Email Backup saves everything as PST, MBOX, EML or PDF files you keep forever, even if the account closes.
- Download Univik Email Backup and install it on Windows.
- Select DNA from the source list. If DNA is not listed, pick a plain IMAP account.
- Give the complete email address with your mailbox password. The login name is always the whole email address.
- When the backup tool wants server details, hand it mail.dnamail.fi on port 993 with SSL. Take those values straight from the IMAP table above, with port
993over SSL. - Pick a saving format and folder, then start the backup. Large mailboxes download in the background.
Email Settings Glossary#
IMAP
Internet Message Access Protocol. Reads mail that stays on the server, so all your devices see the same inbox, folders and read status.
POP3
Post Office Protocol version 3. Downloads mail to 1 device and can remove it from the server. Older method, still useful for local archives.
SMTP
The protocol for sending mail. On DNA the outgoing host is smtp.dnamail.fi on port 465 with SSL or 587 with STARTTLS. Authentication is on with your full address.
SSL and STARTTLS
The encryption DNA uses. Incoming runs over SSL on 993 or 995. Outgoing runs over SSL on 465 or STARTTLS on 587.
DNA Mailbox Password
The password for your DNA mailbox. You reset it in webmail.dna.fi. A new strong authentication is asked afterwards.
mail.dnamail.fi
The DNA incoming server for reading mail. IMAP runs on 993 and POP3 on 995, both over SSL. It is the recommended name since the 2024 merger.
smtp.dnamail.fi
The DNA outgoing server for sending mail. SMTP runs on 465 with SSL or 587 with STARTTLS. Authentication is on with your full address.
webmail.dna.fi
The browser inbox for a DNA address. You sign in with your address and password. You reset the password here.
Welho
The cable brand DNA absorbed. A welho.com address still works, on imap.welho.com and smtp.welho.com or the newer dnamail.fi names.
The New Server Names
DNA merged DNA and Welho mail onto dnamail.fi in November 2024. The older welho.com and dnainternet.net names still connect.
DNA
One of Finland three large telecoms, alongside Elisa and Telia. It runs the DNA email service on dnamail.fi.
dnainternet.net
A DNA email domain from before the merger. An address ending in it still works on the dnamail.fi servers.
Alias Address
An extra address that delivers into your mailbox. DNA allows up to six per mailbox. Older extras from before the change stay until you remove them.
Send Limit
A cap on outgoing mail. DNA allows up to 100 messages an hour and up to 100 recipients on one message.
Sending Address
The address a message is sent from. On DNA it has to be your own DNA address, while a reply can point elsewhere.
How We Verify These Settings#
Univik builds email backup, migration and converter software since 2013. Our tools sign in to DNA 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 DNA 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 DNA shows you? Tell us and we will retest and update the page, with the change logged in what changed recently.
Help & Support
Frequently Asked Questions
Incoming is mail.dnamail.fi on port 993 with SSL. Outgoing is smtp.dnamail.fi on port 465 with SSL. Sign in with your full DNA address and your mailbox password. Turn on SMTP authentication for sending.
DNA merged its DNA and Welho mail in November 2024. The recommended host is mail.dnamail.fi for incoming and smtp.dnamail.fi for outgoing. The older welho.com and dnainternet.net names still connect, so an existing setup keeps working.
IMAP on mail.dnamail.fi keeps your mail on the server, so a phone and a laptop share one inbox. POP3 on the same host downloads mail to one device and can remove the server copy, which suits a single machine or a local archive.
Yes. Every device uses mail.dnamail.fi on 993 for incoming and smtp.dnamail.fi on 465 for outgoing, with your full address and password. Only the menus differ.
A welho.com address uses the same service. You can keep the older imap.welho.com and smtp.welho.com names or move to mail.dnamail.fi and smtp.dnamail.fi. Ports stay 993 for IMAP, 995 for POP3 and 465 for SMTP.
Yes. DNA uses SSL on 993 and 995 for reading with SSL on 465 for sending, so your login and mail travel encrypted. Keep encryption on and avoid the plain ports 143, 110 and 25, which send your login in the clear.
Point a backup tool at mail.dnamail.fi on 993 with SSL, using your full address and password. Let it copy every folder. The backup section walks through it. It keeps a local archive without removing mail from the server.
No. DNA email is for existing accounts only, so new mailboxes are not opened. An existing address keeps working with the settings above. For a new address, DNA points people to Gmail or Outlook.
Add your DNA address to the new account as an IMAP source with mail.dnamail.fi on 993. A migration tool that copies folder by folder works too. Both keep the mail on the DNA server until the copy finishes.
No. DNA Mail has no forwarding on the server, so it cannot auto-send a copy to another address. It also has no calendar. To forward mail, use a full mailbox service such as Gmail or Outlook. You can also download the mail with a client. DNA also caps sending at 100 messages an hour, with up to 100 recipients a message. The section above lists what is left out.
