I run SA... Well the SA libraries wrapped in a .NET assembly. Then used in
an in-house windows port of spamd.
I run the whole thing in an exchange sink, so every message coming into the
exchange server is checked via spamd-nt, takes about a second or less for
each message to be checked; plus gives
sounds like a business plan for turning underpants into profit.
btw: if anybody is interested ive had an experimental c# implimentation of
SpamD running about about a week now on Win32 with great performance on a
10mb global bayes database. If any interest is shown i might release some
code.
