If you're just asking about mail delivery (via SMTP,) then what you have
now is probably what you want.
If you're talking about checking mail (via POP, IMAP, etc,) then no, you
can't do that without also having to do port redirection or somesuch.
If you want to seperate the name you advertise for mail delivery from
the name you advertise for mail checking, then you probably want to add
a couple records:
pop.mydomain.com. IN CNAME mail.mydomain.com.
imap.mydomain.com. IN CNAME mail.mydomain.com.
And then tell your users that the imap server is called
"imap.mydomain.com", the pop server is called "pop.mydomain.com", etc.
