Seznam.cz (Email.cz)
IMAP server:
imap.seznam.cz
Seznam Email keeps IMAP switched off until you turn it on. Until you do, every mail client — mcp4mail included — is refused with a login error, even with the right password. It takes a minute.
1. Switch on IMAP in Seznam
- Sign in at email.seznam.cz.
- Open Settings (the gear icon, top right).
- Go to Email clients (Poštovní klienti, also labelled POP3/IMAP).
- Turn on IMAP access and save.
2. Check whether you need an app password
If your Seznam account uses two-step verification, your normal password will not work for IMAP. Create an app password in your Seznam account security settings (Hesla pro aplikace) and use that instead. Without two-step verification, your normal Seznam password is fine.
3. The settings to use
| Setting | Value |
|---|---|
| IMAP server | imap.seznam.cz |
| Port | 993 |
| Security | SSL/TLS |
| Username | your full address, e.g. jana@seznam.cz |
| Password | your Seznam password, or the app password |
The username is the whole address, including @seznam.cz (or @email.cz,
@post.cz, @spoluzaci.cz) — just the part before the @ is refused.
If it still does not connect
- "Authentication failed" right after switching IMAP on — Seznam can take a few minutes to apply the change. Wait, then try again.
- It worked and then stopped — you may have switched on two-step verification since; create an app password as in step 2.
- You use your own domain on Seznam — the server is still
imap.seznam.cz, and the username is still your full address on your domain.
