you can use mini-sendmail instead of sendmail bin http://www.acme.com/software/mini_sendmail/ normally the sender of your apache is something like www-data etc, which you can limit then, but youre right , if you have many php sites doing this , a typical rate limit policy server might not help in this case A milter MIGHT work since it can be smtpd or non smtpd, not sure, have not found one yet that might do the trick. > > Failing that, or some other simple solution, the simplest thing I can think > of would be to simply watch the log file via a program and by parsing it as > it gets written to, and keeping a count.
