A mail.com address fails to add for one reason above all others: IMAP and POP3 are a paid feature there, and even on a paid plan they are switched off until you turn them on. Work through the steps below in order, then use the server settings at the end.
Start here: IMAP is a Premium feature
mail.com's own help page says it plainly: "the use of POP, IMAP and SMTP are mail.com Premium features only." A free mail.com mailbox cannot be added to BlueMail, or to any other mail app, with any combination of server settings. To use one in a mail app you have to upgrade the account to Premium.
Then switch POP3/IMAP access on
Even on Premium, access is deactivated by default, and mail.com turns it off again "automatically for security reasons if you do not use POP3/IMAP for a longer period of time." In mail.com webmail in a browser:
- In the Email tab, click Settings.
- Click POP3 & IMAP.
- Tick Enable access to this account via POP3 and IMAP.
- Click Save.
mail.com's own instructions: Activate or deactivate POP3 and IMAP.
This is the same behaviour as GMX and web.de — mail.com and GMX are both run by 1&1 Mail & Media.
If you use two-factor authentication on mail.com
With two-factor authentication on, your normal password will not work in a mail app. You need an application-specific password:
- Log in to mail.com in a browser and click the profile icon at the top right.
- Click Security Options.
- Click Manage application-specific passwords.
- Click Create new application-specific password, name it, and click Continue.
The password is shown only once — copy it before closing the window, and enter it in BlueMail in place of your normal password. mail.com's own instructions: How do I set up application-specific-passwords?. Switching two-factor authentication on also means POP3/IMAP access has to be (re)activated by the steps above.
mail.com server settings
| Server | Port | Security | |
|---|---|---|---|
| Incoming (IMAP) | imap.mail.com | 993 | SSL/TLS |
| Incoming (POP3) | pop.mail.com | 995 | SSL/TLS |
| Outgoing (SMTP) | smtp.mail.com | 587 | STARTTLS |

Where these go in BlueMail
Try the normal sign-in first. On the password screen, Allow BlueMail to auto-detect the server details of your account is ticked by default — leave it ticked and tap Next. If that works, you're done.
If BlueMail can't find the details, enter them by hand:
- First account? Tap Continue, type your email address, tap Sign in, then tap Having trouble? Manual Setup under the Sign in button. Already have an account in BlueMail? Go to Settings | Accounts | Add Account.
- On the Choose provider screen, tap Manual Setup at the bottom.
- Choose IMAP (or POP3, for a Premium mail.com account that you want to use that way).
- Fill in the form — it holds the server, Security and Port fields. Pick SSL, TLS or STARTTLS in the Security dropdown to match the table above, and use your full email address as the username.

It worked before and stopped
Check the Enable access to this account via POP3 and IMAP tick box first — mail.com clears it after a long gap — and check that the account is still Premium.
Server details for an account you've already added live under Settings | Accounts | [tap the account] | Incoming/Outgoing Settings — see Edit Account.
