hi,
I've the last stable version of WHM (10.6) on RHE, Exim 4.52.
Too much times the email sent by the server are considered like spam.

This is an example of header of a returned e-mail:

---- ---------------------- --------------------------------------------------
0.3 FORGED_RCVD_HELO Received: contains a forged HELO
1.6 BAYES_50 BODY: Bayesian spam probability is 40 to 60%
[score: 0.5000]
3.6 MSGID_DOLLARS Message-Id has pattern used in spam
1.8 PRIORITY_NO_NAME Message has priority, but no X-Mailer/User-Agent
-2.0 AWL AWL: From: address is in the auto white-list

---- ---------------------- --------------------------------------------------
Total Score 5.3

the main problem is the MSGID_DOLLARS. Can I solve it with Exim configuration?
Thanks for your help

Angelo
