    Only one company we does with has this problem. When I send a message I get
    this return message

    The e-mail system was unable to deliver the message, but did not report a
    specific reason. Check the address and try again. If it still fails,
    contact your system administrator.
    < #4.0.0 smtp;452 Too many recipients received this
    hour. Possible causes might be invalid rDNS (Your DNS PTR record does not
    match your forward DNS entry).>

    This happens about 50% of the time. Is the problem on our end or theres?
    If it is ours, how do we fix it? The only think I can think of is all
    incoming mail goes to XX.XX.XX.11 and all outbound mail comes from
    XX.XX.XX.10 The one is to access the server from the outside world and the
    other is the IP is what I see if go to an IP site and check it.

    Check your domain on and see what it shows about your PTR

    It says PASS

    But like I said before, would the problem have anything to do with a
    diffrent outbound ip the my inbound ip? Thats all i could think of. not
    much of an IT guy here, just sort of tossed into the roll. I try to bump my
    way though. So any more insight would be great.
