Hi Kevin,
The user wants to use the ETRN command with MS Exchange to get messages off the sendmail server so we don't have to use an MX record. How is this accomplished in sendmail? Do I setup a single user catchall?
I saw no replies to your question, so decided to give sendmail.org a spin. Here's what gives: http://www.sendmail.org/faq/section4.html#4.14 In other words: queue it up. HTH... Nico
