I changed the rule name to match a local naming convention I have:
rawbody SA_CUSTOM_TINY_FONT /font-size:\s*[01]\s*(?:p[xt])?\s*;/i
describe SA_CUSTOM_TINY_FONT HTML message contains unreadable font size
score SA_CUSTOM_TINY_FONT 0.1
This went at the bottom of /etc/mail/spamassassin/sa-mimedefang.cf. I plan
on increasing the score tomorrow once I'm sure it's not causing any false
positives...
