I reported one of them to CloudMark and got this... A legitimate organizations phone number was used in some spam so they started flagging all email with that phone number in it (including email from the legitimate organization).
They are clearly WAY overzealous and there is no way their filters should have a default value of 10 in SpamAssassin, in my opinion.
Thank you for contacting Cloudmark.
That fingerprint is for the phone number 972<dash>3341993, which was in messages that were reported spammy by end users and that hit honey pots.
Looking at the feedback I see:
- 80% of reports seen were to block
- 46% of blocks were from spam traps
- 2 ISPs provided spam trap feedback
- First report : 2015-05-13 04:07:18
- Last report : 2015-06-25 09:54:46
It has been legit since 2015-06-24 07:34:22 PT.
