Hi,

I'd like to ask you if the current stable/development version supports filtering through regular expressions?

Yes, both versions support this. In the stable version you can use both match and matchfile. match has a single parameter describing the regexp to match against, matchfile refers to a file containing several regexps (one per line). -- Bazsi PGP key: http://www.balabit.hu/pgpkey.txt, or finger bazsi@balabit.hu
