A client of mine wasn't getting my own hand-typed messages. Unfortunately, they had their SA set to block on a score of 3 (which is aggressive), and this particular rule hit plus a tiny bit of other things put it above 3. But what is weird - is that it was hitting on hand typed-messages from me - that I sent directly from my latest-version of Thunderbird. So this was NOT "forged" at all! (Also, I suspect that the bayes hit was due to previous such messages from me getting blocked and feeding his bayes?)

Any suggestions? Could my client be using a very old version of SA - where this is fixed already? (they are using SA from Kerio).

Here are the headers:

X-Kerio-Anti-Spam:  Build: [Engines: 2.15.8.1169, Stamp: 3], Multi: [Enabled, t: (0.000012,0.017258)], BW: [Enabled, t: (0.000013)], RTDA: [Enabled, t: (0.052863), Hit: No, Details: v2.7.15; Id: 15.1i65djr.1conscun2.ocr1k], total: 0(700)
X-Spam-Status: Yes, hits=3.8 required=3.0

FORGED_MUA_MOZILLA: 2.309, HTML_MESSAGE: 0.001, URIBL_BLOCKED: 0.001,
TOTAL_SCORE: 3.878,autolearn=no

Suggestions?

can you post the headers?
or at least the Message-Id?

SIDE NOTE: I don't think there was any domain my message that was blacklisted on URIBL - so I can't explain the "URIBL_BLOCKED", but that only scored 0.001, so that was innocuous. I suspect that that rule is malfunctioning on their end, and then they changed the score to .001 - so just please ignore that for the purpose of this discussion.
