Rich: Many thanks, we're using *LIST - we fought that "open relay" issue a
few years ago.
Chris: I'm picking my way through unfamiliar terminology here, but we're a
very small shop and don't have a separate mail gateway. If I understand
our config correctly, our i5 smtp server grabs anything that the router
sends to that particular IP address. The email is immediately accepted or
rejected depending on whether there is an SDD entry. I suppose that means
that our gateway and internal server are the same thing? I think I
understand the scenario you are describing but don't think it applied to
our case. Please correct me if I'm missing something.
Now just have to figure out the real problem. I suspect that our domain is
listed as the 'reply to' address on some 'refinance your house' email,
and some AOL'er is tagging our domain as spam.

It is not a relay, but a cleverly crafted email to no
one@xxxxxxxxxxxxxx, with the sender ID of the real destination. That
way if your gateway accepts all incoming email and then forwards to your
internal server, your internal server sends the email back to the phony
sender as a NDR. Your gateway needs to validate all incoming email
recipients and reject if the recipient is an invalid email address.

Subject: Re: I5 smtp and spamcop
JK,
Check your SMTP attributes (CHGSMTPA and F4 prompt it) and see what your
relay setting is set to. If it is set to *ALL, then your SMTP server is
an open relay and they have a legitimate complaint. If it is set to
*NONE or *LIST, then they are all wet.

All,
I've wasted the better part of a day fighting with spamcop.net. They
claim our i5 smtp/pop3 server is a spam source because of "Misdirected
bounces". See below for their FAQ entry. I am relatively certain that
the i5 only accepts inbound smtp if an entry has been made in the SDD
via WRKDIRE and that there is no such thing as a "delayed bounce" in
i5-land. Would someone be kind enough to confirm this or help me
understand what I'm missing?
Many thanks, JK
"Problem: Misdirected bounces Description: When a mail server accepts a
message and later decides that it can't deliver the message, it is
required to send back a bounce email to the sender of the original
message. These bounce emails are often misdirected.
Solution: Upgrade and/or configure your mail server software so that
this situation is never encountered. Configure your software to either
reject messages during delivery or accept them permanently. Do not let
your software make choices about delivery after it has accepted a
message. If you must accept delivery before you know the status of a
message, then file it internally - do not send, forward or bounce it
outside your organization. The errant message can be placed in a special
folder or routed to your postmaster."
