Port 25 is for non SSL SMTP traffic. You cant expect it give you a SSL

Your information is outdated, port 465 is the deprecated SSL-Port. If the
client sends the EHLO command instead of the HELO, then the server can offer
STARTTLS in its capabilities to the client. That initiates a TLS encrypted
connection.

Also port 143 is standard non SSL IMAP port. Port 993 is the SSL port for
IMAP. This is configured in your cyrus IMAP so check the settings there.

This is the real problem. When sending mail the client is connecting to
Postfix. When receiving mails your client talks with Cyrus Imap. It seems that
the problem is Cyrus Imap, not Postfix.
