    Was just perusing my rejected mail log and came upon this:

    Feb 2 00:38:56 reaper postfix/smtpd[30895]: NOQUEUE: reject_warning: RCPT from
    unknown[70.84.96.188]: 550 Client host rejected: cannot find your hostname, [70.
    84.96.188]; from=<xxxxxxxxxx@osnn.net> to=<m.napper@digital-euphoria.net> pr
    oto=SMTP helo=<cryptic.osnn.net>

    someone needs to make 70.84.96.188 reverse to cryptic.osnn.net not 188.70-84-96.reverse.theplanet.com :D

    Someone needs to set postfix to not deny just because it is not set to mail.osnn.net yet.

    Soon it will start sending from mail.osnn.net with proper RDNS, but until the blokes at theplanet get it set up, i can't do anything about it.

    mailexchange.osnn.net correctly resolves to 70.84.96.188

    and 70.84.96.188 resolves to mailexchange.osnn.net

    means some mailservers wont deny mail from you cause the reverse dns of the mailserver doesnt match the domain the email is being sent from. Truthfully though most just complain if they cant find any reverse dns but some are more finiky than others
