Hurricane Electric is not the only hosting company which provides procmail. Procmail is a standard *nix package and is therefore available at all hosting companies which offer Linux or BSD type hosting in combination with SSH shell access.

But you are correct about the functionality and problems of procmail. Although it is very versatile, it needs caveman type of programming and configuration skills to get it working.
