sendmail (Junk Mail)

[Robert Canary]

I did finally get the spamassassin going, however, it looks somewhat 
useless to me.  It seems all it dose is tag email on the subject line 
with the word SPAM.  We already know its spam we don't need it to tell 
us that, we need it to drop it in a black hole.

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.
