Note that if you make apache a 'trusted' user, take care in your script to
ensure that it is not possible for someone elsewhere on the 'net to enter
an arbitary address when http://calling/your/script, otherwise its your
machine sending spam, with no easy way of proving whodunnit.  

If your client can edit the script, do make them sign a provisio that they
will not allow this behaviour, good programming practice, its their fault
if anything goes wrong, should allow for system oddities etc etc.
