rspamd?

A quick browse of the source tarball shows the conf directory has a
bunch of .inc files that have some regular expressions and even meta
rules.

Two thoughts:
1. Any speed tips to be gleamed? (Unlikely given C vs Perl)
2. Any useful rules to borrow?

... actually, a closer look at those rules reveals some or all of them
likely came /from/ SpamAssassin. Sadly, this raises issues about
license violation; no credit is given (a violation of copyright), and
I'm not sure about whether software licensed under the Apache License
v2 can legally be relicensed under the Original BSD License as this
software is. While http://www.apache.org/legal/resolved.html talks
about incorporating sources of various licenses in Apache-Licensed
software, it does not address the other direction.

Re: rspamd? [In reply to]

If they are from sa, that's not good; in our case rules == source.
