Use your assigned UKC server hostname
Use a hostname such as ukc12.uk, as shown for the hosting service or supplied by UKC. It matches the mail certificate and avoids identity warnings. Do not use a raw IP address.
Before setup
Test the mailbox in Roundcube
Sign in to webmail with the complete email address and send one external message. If webmail cannot sign in, fix the mailbox password or service first; repeatedly changing Apple Mail will not resolve a server-side problem.
Mail on Mac
Add the account
- Open Mail and choose Mail > Add Account.
- Select Other Mail Account.
- Enter the sender name, complete email address and mailbox password.
- If automatic discovery fails, continue to manual setup.
- Select IMAP and enter the assigned UKC hostname for both incoming and outgoing servers.
- Use the complete email address as the username for both services.
- Finish setup, then send and receive an external test.
Server Settings
Verify the encrypted ports
- Username
- Your complete email address
- Incoming server
- Your assigned UKC hostname
- IMAP
- Port 993 with TLS / SSL
- POP alternative
- Port 995 with TLS / SSL
- Outgoing server
- Your assigned UKC hostname
- SMTP
- Port 465 with TLS / SSL
- SMTP alternative
- Port 587 with STARTTLS
- Authentication
- Password, required for SMTP
If Mail hides automatic settings, open Mail > Settings > Accounts > Server Settings and disable automatic management only while entering the provider settings.
Common problems
Match the symptom to the setting
- Password keeps returning
- Verify the password in Roundcube and check the full email username.
- Certificate warning
- Use the assigned UKC hostname for incoming and outgoing mail.
- Receives but cannot send
- Check SMTP authentication, port 465 and SSL / TLS.
- Old password persists
- Update both incoming and outgoing server credentials; macOS may store them separately.
Apple Mail still will not connect?
Send us the mailbox address, macOS version, assigned UKC server, ports, encryption choices and exact error. Say whether Roundcube works. Never send the mailbox password.
