    A question for those who have implemented rDNS restrictions.

    In the case of a mail server with roaming users, how do you deal with
    roaming users? A majority of our users travel to conferences and use
    secure IMAP and SMTP to send their mail. Perhaps this is a
    misconception, but I thought that some mail clients attempt to portray
    themselves as a SMTP server relaying through the main mail server. If
    we have users off traveling and having their email is blocked while they
    were connected at a hotel with bad rDNS entries, I'd be getting ticked
    off calls.

    Any suggestions?

    Thanks,
    Mark
