you can's send mail via the proxy unless it's a webmail server (in which
case the origin is most often the webmail service), or the proxy is
misconfigured allowing access to port 25 and there is a client
explicitly designed to abuse misconfigured HTTP proxies for sending
mail.

access.log show all requests sent via squid, from where to where, time,
etc..
