One of our customers is having trouble emailing us. We have no problem emailing them but they get the following NDR when sending to us: A critical function required for the transfer or delivery of the message was not supported by the originator of the report <nts4.ntdom.noodleco.com #5.3.3 smtp;500 5.3.3 Unrecognized command>
We are running Exchange 2000 with SP 3. This is the only domain we are having trouble recieving mail from. Any ideas of whats going on? Thanks, Ed _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:leave-exchange@;ls.swynk.com Exchange List admin: [EMAIL PROTECTED]
