Bug #: 6579
Summary: TVD_PH_BODY_ACCOUNTS_PRE hits on Twitter confirmation
e-mail
Product: Spamassassin
Version: 3.3.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: Rules
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Hi,
TVD_PH_BODY_ACCOUNTS_PRE is hitting on Twitter confirmation e-mail. I don't
have a suggestion for changes to the rule, except perhaps scoring it a bit
lower. I see it is set to the following:
score TVD_PH_BODY_ACCOUNTS_PRE 1.201 1.527 1.327 2.393
Why is the last one (for bayes + net) so much higher than the others? Every
other rule seems to lower the score for bayes + net, as they add to the score
as well.
Lowering this to something like 1.2 across the board should reduce the affect
in FP'ing, yet allow it to be effective against real spam.
I have included the full message, including headers, where it would have FP'd.
In my setup, I have manually rescored the rule.
