Nope. For the perl version, spamd+spamc solution (i would call it a messy hack) is a workaround for perl's 'booting/startup' overload. For the C version, there is no such overload, by storing precompiled regexps in file (or compiled-in data) i can reduce 'booting' time to <5ms. (currenty it's ~12ms on p4). I don't like the idea of sending mails through the (local) network to a daemon and then get the results back... it's a really big overload compared to C version, while it still much better than restarting the perl version for each mail... > But writing a forking server in C is fairly tricky, at least to get it > right.

And then only if it showed better performance. I don't even plan to implement 100% compatible alternative, i'll probably leave some checks out. At least now i won't implement all that eval's in C, and will leave all network tests (they can be done by the MTA if needed). Anyway I have some idea to speed up this thingie even more. For example, doing the regexp checks at 2-3 passes. First the cheap (fast) ones, and the big (high score) ones. Then if score <=0 i'll stop and return NO_SPAM. If there was any positive score at first pass, i'll continue with expensive (slower) checks. It will probably lower check quality a little bit (more possible false report) but increase performance a lot (n times). For this i have to do some statistics analyzing of negative/positive hits on a big enough spam and nospam collection. It will also slow the less used checks, they may be left out, or at least moved to 2nd/3rd pass... So, again, the goals are a bit different. I don't plan to do 1:1 rewrite of spamassassin or spamd program!
