Domain name mismatches in SSL certificates
Finally a solution to the warnings of mismatched domain-names when using SSL for IMAP and/or POP. If your like me, and query several different domain-names served by a hosting company, the domain-name of the actual machine queried for IMAP and/or POP (the reverse DNS lookup) will differ from that of your domain-name. The email client then thinks something is suspicious and barks at you for every account and you have to interact by telling it it’s “ok to continue.” If you have several accounts this can get annoying, as every time you open your email client you will be prompted once for every account. And if you use SMTP over SSL, you’ll get the same thing when trying to send. I finally found some fixes for this problem.
