that I had a large amoutn of spam email originating from one of our work
servers. I tightened up the postfix rules, and cleared the queue which appeared
to fix the problem.<o:p></o:p></span></font></p>

font-family:Arial'>Two weeks on, its started again, and I've just noticed that
all messages seem to be originating from www-data@domain which leads me to
think it must be some rogue process in apache which is causing the problem.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My problem is, that I don't have any idea of locating where
the cause of the problem is, I've checked all htdocs directories, and the only
scripts are php scripts which I've written, of which none contain the use of
phpmailer() or mail(). The only thing I can think of, is someone is somehow
spamming from www-data elsewhere.<o:p></o:p></span></font></p>
