I’m using google apps for my email. Configured it like this:
Incoming Mail (IMAP) Server - requires SSL: imap.gmail.com
Use SSL: Yes
Port: 993
Outgoing Mail (SMTP) Server - requires TLS: smtp.gmail.com
Use Authentication: Yes
Use STARTTLS: Yes (some clients call this SSL)
Port: 465 or 587
But how do I use other named servers, where you don’t see gmail.com? Like imap.mydomain.com instead of imap.gmail.com. same for the outgoing server.
is it possible with changes to my DNS settings?
If you really want to do it, you can setup some CNAMEs in your DNS zone:
It would still be pretty easy for someone to figure out you’re using Google Apps, though this will hide it from and end-user who does not care to look this up.
