    email bounced for container policy reasons

    E-mail sent from a Geeklog CMS site is being rejected by a specific domain with the rejection message:

    550 5.5.0 Mail rejected for container policy reasons

    Any ideas on what this means?

    This is apparently a recent change, and the domain's email adminstrator has not responded to my requests for an explanation.

    I'm not sending unsolicited mail. This happens when I attempt to communicate with registered users who have previously signed up using email at this domain.

    a 5.5.0 error is normally a generic transport error and most times due to reverse lookups failing for the intended domain.

    If you want you can try and telnet to the smtp server that is giving you problems and try and send a message so:

    C:\telnet meanserver.meandomain.tld 25

    220 mail.meandomain.tld ESMTP Postfix
    helo itsmedomain.com
    250 mail.meandomain.tld
    mail from:[email protected]
    250 Ok
    rcpt to:[email protected]
    554 <[email protected]>: Sender address rejected: Domain not found

    That is close to what you should see if this is the problem.
