It appears to me that all mail coming through Yahoo groups is getting
at least 4.5 points because of yahoo's use of tiny fonts and of
non-compliant Date: formats. Here's the spamassassin analysis:
pts rule name description
---- ----------------------
--------------------------------------------------
2.2 INVALID_DATE Invalid Date: header (not RFC 2822)
0.1 HTML_90_100 BODY: Message is 90% to 100% HTML
0.0 HTML_MESSAGE BODY: HTML included in message
0.0 BAYES_50 BODY: Bayesian spam probability is 40 to 60%
[score: 0.5000]
2.3 HTML_TINY_FONT RAW: body contains 1 or 0-point font
And below, here's a segment of the headers; I'm reluctant to post the
whole thing, because it's not my mail. I have included every one of
the "Date:" headers, though.

(The "..."s are inserted by me, of course.)
Now, I took a quick look at rfc 2822, and all of the Date fields in
this e-mail would appear to be compliant. So: is there a bug in
spamassassin's Date parsing, or is yahoo committing some subtle bug,
or is the mailer's original date somehow non-compliant?
Many thanks in advance,
John Clements
- why are there multiple Date headers?
- the date fields look ok indeed.
