So, squid understands "CONNECT". Everyone, even me, and obviously you,
understands that, but as you, yourself point out in a later email, it's
totally useless to an email client. You have to run something else. Squid,
on its own is no use for email.

So, Glen's sensible options are:

=09- run an MTA
=09- run a SOCKS daemon
=09- allow clients to talk SMTP to internet
=09- run an SMTP "proxy" (eg smap from fwtk)

Oh yeah then he could also

=09- run a proxy that mail clients talk to and have it talk to squid
=09and use the CONNECT method

I know which way I'd go.
