Would any one care to comment on this:

Our company's outgoing e-mails are consider to be spam, so they are being block by some of the receivers.

What type of configuration on the Exchange 2K (if in fact it is the Exch)will cause to flag the e-mails as spam e-mails?

Any comments are appreciated.

Regards

Jorge

If your server was used as a "relay" for people spamming others. One of the ways other admins will react will be to filter out your domain. Or your domain may be on a Blacklisting server.

"Blacklisting" blocks delivery of ALL mail from sites that allow open relaying. This is done by using "Real Time Black Holes" (RTBH), databases that list sites known to deliver spam, whether they meant to or not. Sites that want to eliminate spam can set their mailservers to query these databases to determine if the source site is a "known spam site", and reject any mail from servers on the list. One of the primary criteria for being listed in RTBH is having an open relay -- it doesn't matter if any spam is actually being sent through your open relay, RTBH databases will blacklist you because spammers could send spam through your open relay.

See if you can relay through your servers. Correct it. And have blacklisting sites test and remove your domain once the problem is resolved.

Check Microsoft Knowledge Base article Q310380 for instructions on how to disable mail relaying on Exchange 2000.
