Fix IMAP Connectivity on Webuzo

Here’s the situation: I run a Hostinger Alma-Linux VPS with Webuzo installed. Mail for my domain ttownmen.org sends and receives fine through the built-in webmail, yet any external IMAP client—specifically Spark and EspoCRM—throws a straight connection failure when set to SSL/TLS.

I’ll give you both SSH and Webuzo panel access. The test mailbox is

• Username: test @ttownmen.org
• IMAP host: mail.ttownmen.org
• Password: test1234qwerty

Your job is to log in, inspect my Webuzo mail stack (Dovecot, Exim, certificates, ports, firewalld, etc.), identify what’s blocking the SSL/TLS handshake, and apply the fix. When you’re done I need:

1. Spark and EspoCRM connecting normally over SSL/TLS on the standard secure ports.
2. A short note outlining what you changed so I can replicate it on future domains.

That’s it—once both clients sync without errors the task is complete.
