    I am getting the following problem.

    2007-04-15 22:56:57 1HdIKG-00069C-5V == test@domain.com R=lookuphost T=remote_smtp defer (-44): SMTP error from remote mail server after RCPT TO:<test@domain.com>: host mail.domain.com [x.x.x.x.x]: 451 Temporary local problem - please try later


    I have did following:

    /scripts/updateuserdomains
    /scripts/mailperm

    and double check the resolver and make sure it is working.

    But i still can't get the email to deliver.
    what could be the problem?

    Go on, have a guess
    Since that is a remote error, then the problem is on the recipient server and you can only determine what that problem is on that server. If it's not your server that's the recipient then you'd have to contact its server admin to have them check their logs.

    I disable "Verify the existence of email senders." in order to get it working. Hope others find this useful.

    If there is a wrong forwarder for the recipient domain then you will see such error.
