[squid-users] Controlling Spam

We block port 25 so our users can only send mail using our SMTP server.
However we suspect that some users get around this restriction by sending
outgoing SMTP using port 80. I would like to block SMTP traffic by port
using Squid. If this is not possible is there a way I can 'sniff' and
'intercept' SMTP traffic?
