It has happened many times that the emails from our server were identified as spam. I have checked the emails which were not identified as spam. But I found that the SpamAssassin Scoring For MDAEMON_DNSBL is quite high, the score of MDAEMON_DNSBL is always 4. I also checked the logs of SpamAssassin and here are some messages:
Is this a local SA install, or some third party testing service? If the latter, who?
Performing DNS-BL lookup * zen.spamhaus.org - passed * bl.spamcop.net - passed * bad.psky.me - failed - 198.54.117.200
That doesn't appear to be SA related. Is that just informational related data?
* 1.6 BAYES_50 BODY: Bayes spam probability is 40 to 60% * [score: 0.5000] * 4.0 MDAEMON_DNSBL MDaemon: marked by MDaemon\'s DNSBL * 2.1 FREEMAIL_FORGED_REPLYTO Freemail in Reply-To, but not From
I still don't know what's reason for such a high score for MDAEMON_DNSBL
That rule is not in the base SA ruleset so we can't help you analyze it. I suggest you contact MDaemon to see why you're listed.
and why FREEMAIL_FORGED_REPLYTO got 2.1 score?
The answer to that question for base SA rules is always: because it looks like a fairly good spam sign based on the masscheck corpora.
If those are emails you are generating, then why are you using a freemail address for the Reply-To: address them but not the From: address?
Providing the headers from such a message would make it easier for us to provide a more substantive analysis.
