    Thank you all for your help. The issue is now resolved, in an ass backwards sort of way. We purchased a VPS and set up a smtp proxy on an obscure port and mail is now being processed.....

    We encountered some mail systems where they checked each hop in the received list and if each and every one could not be reverse resolved, the mail would bounce. And even if they resolved, they were checked against the PBL. We had to add some internal mail servers to our external dns because of this. I would have preferred just to let the mail bounce, but since they were customers, we had to bend.

    Designing a mail system that paranoid is certainly up to individual sites, but they shouldn't be surprised when legitimate mail bounces. Even if you are doing this, it should be to setup a score and mark the header, rather than bouncing.

    Hi Blake -
    With Godaddy The 554 code is a tipoff.
    Does the error also contain the text:
        SMTP error from remote mail server after end of data:
        host smtp.where.secureserver.net [xx.xx.xx.xx]:
        554 The message was rejected because it contains prohibited virus or spam content
    GoDaddy has an unusual policy of rejecting any email that mentions anything that resolves to an IP address on the PBL list
    Note this means any text string with the email body itself, not the originating IP of the email.
    Any text, a URL or a even a dotted quad that resolves to the PBL list will cause the email to blocked.
    By way of example, this policy blocks emails from amazon ec2 merchants even if the email only mentions a web site hosted at ec2, and the email itself is from a static web server with proper MX records.
    They have been contacted multiple times over the years about this issue and refuse to change their policy.  The PBL list explicitly describes how to use their list and this way of using it is incorrect.  The PBL list is supposed to be used to check the IP address of the system actually delivering the email to your server, not the contents of the email.
    Based on their long term refusal to adjust their policy to conform to PBL intended usage of the list I suspect this issue cannot be corrected.  The only answer I have found is to inform the affected people they have to move from GoDaddy to a company that does a better job to correct the problem.
    If this is NOT the issue creating your problem, then you may be able to get GoDaddy to do something to help.
    Good luck.
    Jeff Kinz.
