This was discussed before but somehow nowhere is no satisfactory conclusion or solution to this as of now.
I am trying to find out why my messages getting marked in http://isnotspam.com with a 3.5 BAYES_99 BODY score. It is nice that the report shows “SpamAssassin Check : ham (non-spam)” However, it bothers me that I get:
3.5 BAYES_99 BODY: Bayes spam probability is 99 to 100% 0.2 BAYES_999 BODY: Bayes spam probability is 99.9 to 100%
So yes, its not really market as spam but how could it even look like spam for the Spamassassin BAYES? I thought it might be my HTML signature or the fact that the email was sent as HTML. So, I tried a version with only a JPG as a signature, and then finally the version that can be accessed on the link below that is pure text only. Still the same result. I checked if the IP or domain is blacklisted anywhere, but all is clear. My emails are signed with SPF, DKIM, DMARC and are even listed at dnswl.org as trustworthy.
It is frustrating that even though emails would most likely be delivered because it gives a score of 2.7, but still, it is not pleasant to be classified as 99% probable spam and I feel like a score of 2.7 is still high. You never know how other receiving servers have configued the spamassassin score for this.
I would appreciate if anyone has an idea on what else to check. The sending email server is CentOS 6.9 with Postfix, AMAVIS-New, ClamAV. I am not sure what else this could be, see the link below to the report; it is a text-only email. Thank you for everyone that can assist me in getting this resolved.
Best wishes, Thom
