Author smtp issue

2006-02-07, 6:02 pm

Hi all, I have a domain network and am having an issue sending out email via
the smtp server. If I use OE on the actual SMTP Server itself then the email
goes through fine. If a client on another server in the network tries to
send it, I get the following NDR:-

You should look at the SMTP server logs -- NDRs are a first cue that
delivery has failed, but the "meat" will always be in the logs.

In this case, my best guess is that you are using the unpublished
..local domain to originate mail to the outside, and some link in the
chain is choking on address verification.
