best way to submit patches

A few weeks ago I submited a patch to improve open_basedir with dynamic virtual hosting directly to rasmus@lerdoff.on.ca and jimw@php.net (developers listed in the source file I modified). I have not heard from them, and I am under the impression that emailing the authors directly is not the best method for sending patches. I will probably send modifications from time to time, but I don't want to become an annoyance. Would someone mind emailing me the prefered method? Thanx Jason
