Quoting Karsten Bräckelmann <[email protected]>:
Please see bug 6155 comment 128. https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6155#c128 The issue persists, and being an onet.pl customer using The Bat! MUA is kind of a deadly combination. Those are being shot single-handedly. score KB_DATE_CONTAINS_TAB 3.800 3.799 3.799 2.751 score KB_FAKED_THE_BAT 2.432 3.441 2.008 2.694 Comments? Is this something we need to worry about? I do, rather scary to me. :/
If the rule KB_FAKED_THE_BAT looks for the X-Mailer header, you can always tell The Bat! not to place the X-Mailer header. I use the professional version of the email client on my personal email account and have it removed as there is a telco around here that flat out rejects messages that bare the X-Mailer header sending from The Bat!.
