Hi All, I'm getting a bounced mail message for one of my users trying to send mail to an account at AOL. I know we can mail AOL, because I do it daily. I went on to AOL and checked the address (by sending them a mail from my own AOL account), and it's a valid address. Here's the paste of the rejection message: The following recipient(s) could not be reached: 'bmiltchev@xxxxxxx' on 9/22/2003 4:32 PM The recipient name is not recognized The MTS-ID of the original message is: c=US;a= ;p=TCR;l=TCRNYCBDE2-030922203137Z-1464 MSEXCH:IMS:TCR:TCR:TCRNYCBDE2 3550 (000B09B6) 550 INCORRECT DOMAIN IN MAIL/RCPT COMMAND Anyone have any ideas what could be wrong here? I'm using Exchange 5.5. Thanks, Gene Gene O'Brien Network Administrator Three Cities Research (212)605-3229 gene@xxxxxxxxxx
