  • Exchange 2010 & Sonicwall bounces

    Hi,
    Im trying to diagnose some message delivery problems from our exchange organisation to another (not connected, completely seperate). For the life of me i cant work out why its happening!

    Heres the bounce that users get:

    emailsecurity.theirsystem.com<http://emailsecurity.theirsystem.com>.

    I am sending you this message to inform you on the delivery status of

    of the affected recipients;**also attached is a Delivery Status
    Notification
    (DSN) report in standard format, as well as the headers of the original
    message.

    Ive replaced users, server names, IPs, ect; for obvious reasons.

    Anyone got any ideas why this is happening?

    Put their external IPs in the white lists for our spam solution, in transport rules, ect; yet it still seems to be bouncing.

    Thanks.

    You said the problem is sending email from you to them but the DSN appears to be for an email from them to you, so which is it?

      Exactly how youve said....they seem to have some device that sits on the edge of their network that does most of Exchanges job for it. Or so i can make out. Hence the wierd bounce message. I THINK its a SonicWall.

        Whatever device is doing the sender filtering (presumably the Sonicwall as it says it in the headers) you would need to ask the remote host to white list your email address.
