Spamassassin tips?

[Scott Garman]

Welcome back, GNHLUG. You were missed. :)

For the past few weeks I have been getting deluged in financial-related
spam, particularly debt consolidation and forgiveness schemes.

A while back I enabled some of the network checks (e.g, razor) and that
dramatically reduced the amount of spam that got through my filter. I'm
running spamassassin v3.2.4 on CentOS v5.2.

A common characteristic of the recent spam is that it uses accented
characters and misspellings (presumably) to avoid having spammy keywords
matched. For example:

dêbts
reqùireed
credït

Through googling I found a ruleset that weights non-Western character
sets high as spam, but that works more for Russian and Mandarin spam
than the accented characters above.

Does anyone have any suggestions or rulesets they could recommend to me?

Thanks,

Scott
