[clamav-users] signature that penalizes for line length?

[Vincent Fox]

Hi,

We use ClamAV, and I have noticed a certain class of spam hitting us lately
that has VERY long final lines of garbage text.

The reason I noticed it was the length exceeds 2048 characters, which trips
a problem in POP3 client downloads.

Anyhow is there any signature that can be used to score and penalize
text/plain messages with excessively long lines?

Thanks!
