Exchange 2000 smtp relay still open after applying no relay poperties

Post by Jason Irwi » Wed, 10 Dec 2003 22:46:37


I was getting a lot of badmail entries and found that our exchange server
had the SMTP relay open. I Used the exchange system manager to go to:
Servers; Server1; protocols; SMTP. Then I right click on the default SMTP
server and selected properties. I verified that the only allowed addresses
that can relay to the default SMTP server are from our private network of
192.167.1.0 subnet mask of 255.255.255.0 and the single ip of 127.0.0.1 (
even tried removing both of these and still getting a lot of badmail.) Our
15 users don't send over 100 emails a day so the volume badmail should not
be growing that fast. Any suggestions? I did try to enable basic
authentication on the default virtual SMTP server but when I do that we do
not receive any email.
Any suggestions?

The files in the badmail directory are probably there becasue they
they're SPAM and the address to which the NDR should be send was
frged.

Rich,

So is the user "stuck" with the growing # of BADMAIL entries until
all SPAMMED emails are done 'failing' or is there someplace that they
can be blocked so that they are no longer received into BADMAIL and/or
to the exchange server in question

They're "stuck". But you can schedule a batch job to run every so
often to delete the contents of the directory. How often depends on
how fast the files accumulate.
