Bug with HTML messages?

[Denis Beauchemin]

  Hello,

I just deployed the latest MS (4.80.10) on a fully patched RHEL 5.5 
system and it is behaving strangely with HTML-only emails in Thunderbird 
3.1 (didn't test others). I tested it with an email with plenty of spam 
content but it got delivered with a really low score: 1.5. I then tested 
it with the same email sent with *both* HTML and text and it got a score 
of 13.

Could there be a problem with some Perl-HTML module?

SA scoring for HTML-only email: SpamAssassin (not cached,
     score=1.542, requis 4.5, HTML_MESSAGE 0.00,
     HTML_TAG_BALANCE_HEAD 0.82, MIME_HTML_ONLY 0.72,
     TVD_SPACE_RATIO 0.00)

SA scoring for HTML+TXT email: (not cached,
     score=13.313, requis 4.5, BAYES_00 -1.90, DEAR_SOMETHING 1.97,
     DRUGS_ERECTILE 1.99, DRUGS_ERECTILE_OBFU 1.11, DRUG_ED_CAPS 0.94,
     HTML_MESSAGE 0.00, KAM_VIAGRA1 3.00, KAM_VIAGRA5 3.10,
     KAM_VIAGRA6 3.10)

Am I the only one with this problem? I was also able to replicate it on 
a much older MS setup (v. 4.63.2):

SA scoring with HTML-only email: (not cached, score=12.639, requis 4.5, 
autolearn=spam, DEAR_SOMETHING 1.60, DRUGS_ERECTILE 0.28, 
DRUGS_ERECTILE_OBFU 1.23, DRUG_ED_CAPS 0.32, HTML_MESSAGE 0.00, 
KAM_VIAGRA1 3.00, KAM_VIAGRA5 3.10, KAM_VIAGRA6 3.10)

SA scoring with HTML+TXT email: (not cached, score=7.181, requis 4.5, 
DCC_CHECK 2.17, HTML_MESSAGE 0.00, HTML_TAG_BALANCE_HEAD 1.33, 
MIME_HTML_ONLY 1.46, TVD_SPACE_RATIO 2.22)
