The settings are the same whatever the program.
WHAT ANY CLIENT NEEDS
- Account type: IMAP
- Incoming server: mail.yourdomain.com, port 993, SSL/TLS
- Outgoing server: mail.yourdomain.com, port 465 SSL, or 587 with STARTTLS
- Username: the full email address, on both incoming and outgoing
- Password: the mailbox password
- Outgoing authentication: enabled, using the same credentials
IN EM CLIENT
Menu > Accounts > Add Account > Mail. Enter the address, and when automatic setup fails choose to configure manually. Enter the values above.
IN MAILBIRD, BLUEMAIL AND SIMILAR
The wizard differs but asks for the same six things. Look for an option labelled Manual, Advanced or Other rather than accepting the automatic guess.
WHY AUTOMATIC SETUP OFTEN FAILS
It relies on published configuration records that shared hosting does not generally provide. Manual setup takes two minutes and works first time.
IF THE CLIENT INSISTS ON DETECTING
Enter the server hostname from your welcome email rather than mail.yourdomain.com, which sometimes satisfies a stricter certificate check.
