Is the @customerdomain your inbound one? If so, than the behavior seems correct to me as you are not relaying. You were authenticated as an user.

When clamping down on relaying I get relaying prohibited messages when spoofing a fake recipient domain via telnet - as expected no problem. However, if I send to a non existent recipient at the correct domain (say someonewhodoesnotexist@customerdomain), and include an attachment I receive an NDR with the attachment. Am i correct in thinking this should NOT be the case and that something on the box is screwy (else in effect you can deliver the attachment in an NDR by spoofing the from address?) details - one inbound domain, reroute incoming SMTP mail checked, and routing restrictions set to "hosts and clients that successfully authenticate" thanks David _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
