I agree, but "advanced PHP programmers" don't even think about checking return value of mail() function that invokes sendmail.
If they don't, the "advanced" adjective should not really apply.Failure to check exit codes, and assuming that anything, mail(), or something else, will always succeed, is a newbie mistake.
It wouldn't surprise me too much if those same "advanced PHP programmers" would also have a habit of not properly validating input parameters, which would lead to all sorts of interesting ways of using their PHP code.
