We recently upgraded to sendmail version 5.61 and we've noticed an annoying
behavior. When a network client tries to send to a mailing list that
contains one or more invalid local addresses (as well as some valid
addresses), the response to the RCPT TO command is 550, which causes the
client to abort the entire delivery. By doing a manual telnet to the SMTP
port I discovered that if the client were to continue the message would be
delivered to the valid addresses; but normal clients have no way of knowing
this.
Is there a way to get sendmail to accept the message and send its own
failure notice back to the sender describing the individual addresses that
failed?
Please reply to bug-mailers@think.com; our newsfeed has been pretty
sluggish lately, and not all of us read this newsgroup.
