[aclug-L] Re: MTAs & maildir vs mbox (was Re: Virtual POP3 and IMAP server)

[Jonathan Hall <jonhall@xxxxxxxxxxxx>]

The familiarity factor is the main reason I've not seriously considered
straying away from sendmail until now...

And the only real reason I'm considering swiching now is b/c I can't find
any POP3 and IMAP servers that like to cooperate with sendmail *and* virtual
domains.
