Mails Bouncing RRS feed

  • Question

  • Hi,

    I am facing issues with our exchange 2003, when some user trying to send mail to external it is bouncing back with following messages "

                You do not have permission to send to this recipient.  For assistance, contact your system administrator.

                <wafiexch.wafigroup.local #5.7.1 smtp;554 5.7.1 Message refused by Heuristic check. 9.9.9>

    " but if i remove the signature and try to send, it going through. Please advice how i can proceed to fix the issue.
