As far as I know, there's no way you can do this via PHP. PHP doesn't "know" about users on the system. Generally, PHP is run as an apache module, and thus the scripts are run as the user apache is running as. So to start with, you'd probably need to be running a Fast CGI + SuExec setup or something similar. I'm not sure how, or if there is a way to do this in postfix. The mail() function calls the sendmail binary, so one sort of hackish way might be to move this binary and write a wrapper script that keeps track of per-user rate limits, and then invokes the real sendmail binary. Of course, in this case, you'd also probably want to make sure the real sendmail binary couldn't be executed and that users could not write to the file that keeps track of the rate-limit. -- Greg On Tue, Apr 8, 2008 at 12:37 PM, Jordi Moles <jordi@xxxxxxxxx> wrote: > hello everyone, > > first of all... i'm sorry if this has been asked like a million times > before... but i've been looking for info about this and found nothing so > far. > > anyway.... > > I've got a server with apache2 and postfix and php5 providing hosting to > some clients.
