The settings are the same everywhere; only the screens differ. cPanel will also show them for any mailbox: open Email Accounts and choose Connect Devices.
The settings
- Incoming – IMAP, port 993, SSL/TLS
- Outgoing – SMTP, port 465, SSL/TLS
- Server – mail.yourdomain.co.uk
- Username – your full email address, not just the part before the @
- Password – the mailbox password, which is not your cPanel password unless you made them the same
- Outgoing server requires authentication – yes, with the same details
IMAP, not POP
IMAP keeps mail on the server and synchronises, so what you see on your phone matches your computer, and deleting in one place deletes everywhere. POP downloads and often removes mail from the server, which causes the classic problem of messages appearing on one device and vanishing from another. Unless you have a specific reason, use IMAP.
The two usual failures
- Username entered without the domain. It must be the full address.
- Outgoing authentication left off. Mail arrives but will not send.
Certificate warnings
If you use mail.yourdomain and see a certificate warning, the certificate for that name has not been issued yet, usually because the domain has only just moved. It resolves itself; in the meantime use the server hostname, which always has a valid certificate.
After changing a password
Update it on every device. A phone left retrying an old password will get your address blocked – see Why we block IP addresses.
