Hetz,

  Regarding spam assassin - any test mail simply goes to spam, even a
  simple: echo Hello World | mutt [EMAIL PROTECTED] -s This is an
  email test - goes directly to spam.

SA also has tests for suspicious headers, RFCs noncompliances etc. so
it might as well be useful in detecting the culprit.

I guess they have different IP addresses...
Could it be the these 2 are blacklisted?

 Hi,

 I have here 4 Linux machines, which will be running some forums, db etc...

 2 of the machines, when testing to send mail to gmail, send it and I
 recieve it correctly. However, 2 other servers when they send mail,
 the mail goes directly to the SPAM folder in gmail.

 I can do the simple trick of clicking the message and clicking not
 spam, but the 2 servers do need to send registration mail to users,
 and if they'll get the mail in the spam it will cause tons of
 problems.

 I have checked the RDNS, sent mail not from root, SPF record is OK.
 (mail server is sendmail).

 Have I missed something? I checked all the servers and they have the
 same config.

 Thanks,
 Hetz

It's hard to tell how gmail filters its spam. I bet it's an Intellectual 
Property of theirs. 
However, you might get a clue if you run the problematic email through 
spamassassin (use 'spamc -R  your_email') and see which spam tests are being 
hit.

If you don't have a working spamassassin configuration, send the file to me, 
I'll do it for you.

Yuval,

I had checked on all the usual suspects of blacklists - spamhaus, RBL,
etc. Those 2 machine's IP are not blacklisted.

Regarding spam assassin - any test mail simply goes to spam, even a
simple: echo Hello World | mutt [EMAIL PROTECTED] -s This is an
email test - goes directly to spam.
