Are the clients configured to use the same name defined in the certificate?
We found that if the certificate is for "mail.domain1.com" the clients must use "mail.domain1.com" as the SMTP/IMAP hostname even if "mail.domain2.com" is pointed to the same IP address unless the client software has the option to allow any valid certificate.
