Mailfence Not Working? Login, Locked Accounts and Email App Fixes

Mailfence problems usually come down to the login identity, the account's status, or the plan. Work through the section that fits.

The login fails

• Use your username or primary address, not an alias. A red field means the username or password is wrong.
• Type it yourself. If a password manager's auto-fill is rejected, copy and paste the username and password into the fields.
• Fix the browser: clear the cache, restart, enable JavaScript, cookies and session storage, try a supported browser and disable extensions.
• Lost the two-factor phone? Use one of your backup codes.
• If none of that works, reset the password — see resetting your Mailfence password.

The account is suspended or locked

Mailfence lists five reasons an account gets locked or suspended:

1. Inactivity — free accounts are suspended after 7 months unused and deleted 5 months later. Upgrading to a paid plan reactivates the account.
2. Spam from a compromised account, which trips the anti-abuse system.
3. A Terms of Service violation.
4. An unpaid subscription.
5. A technical fault.

To unlock it, email Mailfence support from your reset/notification address, giving your username or email address and your subscription package. Expect extra identity checks.

An email program won't connect

• Check the plan. IMAP, POP and SMTP are paid-plan features; a free account won't connect from Thunderbird, Outlook or Apple Mail.
• Check the login. Use the primary address or username, not an alias — even if the alias is a valid From address.
• Check Services access (Settings → Account → Security). Connections from a disabled service are refused, so if one protocol works and another doesn't, make sure that service is enabled.
• Check the password. If you use service-specific passwords, the program needs the one made for it, not your webmail password. Two-factor codes aren't used by email programs at all.
• Check the history. Connections history (under your account display picture) shows failed SMTP-IMAP/POP attempts, which tells you whether the program reached Mailfence and was refused.

Server names, ports and encryption are in Mailfence server settings.

Something looks wrong

Successful logins you don't recognise in Connections history may mean someone else has your password. Change it under Settings → Account → Security, revoke service-specific passwords you don't need, and follow Mailfence security. For anything else, contact support@mailfence.com with your username.
