Christian, > If I understand correctly, this code is in the 2.5.3 version already ? No, it is a freshly reported bug, introduced in 2.4.1. The fix is not yet in any released version. The provided patch was for 2.5.3. With some fudge it may apply to earlier versions as well. It will be fixed in 2.6.0. By itself it is not serious enough to warrant a 2.5.4, so unless something more sinister pops up, there are currently no plans for 2.5.4.

You are quite right, it is an ugly bug, the header field is saved under an
incorrect name and later not found when tag is to be inserted into Subject,
so a new one is entered. Here is a fix (diff against 2.5.3, likely to apply
to earlier versions as well):

I personally prefer not to tag the subject. Real(TM) MUAs have no problems parsing the X-Spam-Flag header... PS.

[AMaViS-user] Subject line oddities...
Have had a few messages getting through lately that should have been tagged as spam but appear not to have the subject line tagged. I check the headers and see (some headers removed)... X-Spam-Flag: YES X-Spam-Score: 9.498 X-Spam-Level: * X-Spam-Status: Yes, score=9.498 tagged_above=2 required=5 tests=[BAYES_99=3.5, GOOG_PAGES=5, NO_RECEIVED=-0.001, NO_RELAYS=-0.001, URIBL_GREY=1] Subject: :: 86% Cheaper than Original Price: aRolex, Cartier, Omega, Chanel, Tag Heuer, Breitling & ... qfbvvqgron Subject: [SPAM -> 9.498] So when the email is viewed in Outlook (only reader I've tried so far) the original subject line is shown without spam tag. S... what's the trick that's making Amavisd create a new subject line instead of adding it to theirs? Is there a way to fix so the tagging happens properly? Running amavisd-new 2.4.4 Cheers, > Mike < - This SF.net email is sponsored by: Microsoft Defy all challenges.
