Especially when using a fake email in the from header. I tried testing it from the telnet prompt and manually feed bogus mail headers. Ironically sendmail took both the to and from bogus headers. Sendmail did kick it out if I used a bogus domain.
How do you tell sendmail not to except connections for bogus incoming email. I would have sendmail.org would have thought of this the same way they did of requiring a valid domain name.

I have been looking at the spamassassin for about two days now. I know the solution has somethin to do with spamc which interfaces with spamd.

Of course sendmail sends a response back to the from header saying the account dosen't exist. However, the sendmail server is getting those responses bounced back to them because these are junk emails with no real return address. As a result the undeliverable mail gets sent to "postmaster". Thus the "postmaster" email is a hoard mess of junk email bounced replies.Install spamassassin and reject spams. also configure SPF. This should solve your problems.How is being handled ? -- robert
