I had a similar problem, but some time back and I can't remember 
*exactly* what I did. It was something like pointing mailer.conf to my 
own program which did some logging and then called the real sendmail. 
Actually, I might just have hacked mailwrapper directly. I think there 
was some way I managed to cross-reference to the httpd logs, or that 
might be what I tried to do and failed. Sorry - this may not be helping 

Another approach might be to find some likely text in the outgoing 
message and do a recursive grep on /home.
