Does anybody have any idea why my postfix server accepted mail
for the
non-existent user "<squir...@webmail.cnysupport.com>" (no alias
by that name either)?
I've narrowed it down to a problem with the way subdomains users
are
validated.
badu...@cnysupport.com is properly rejected at the rcpt to:
command,
while badu...@whatever.cnysupport.com is accepted, then causes an
NDR.
Anybody have any ideas?
Yes. As you were already told, set in main.cf
relay_domains =
ie. set explicitly to an empty value.
That worked, however I was not "already told" anything, except Charles
Marcus' recommendation to post postconf -n, which I did.
The subdomains weren't listed in mydestination, relay_domains was not
set, which should default to mydestination.
In any case, According to
http://www.postfix.org/postconf.5.html#relay_domains, the relay
recipients are supposed to be validated against relay_recipient_maps.
Since I don't have a relay_recipient_maps, it should reject anybody
who isn't a local user.
It's working, and I appreciate the help, but I'm either
misunderstanding the docs or something is behaving improperly.
