I've never liked TURN and ETRN, somehow ... and yeah - port 587 (smtp-auth)
doesn't work too well on some ISPs (Earthlink / Sprintlink, forgot which)
which have been filtering port 25. AOL does this too - in a different way.
If you try to relay through another server, AOL forces this request through a
set of smtp proxies (rly-ipXX.proxy.aol.com and tot-tX.proxy.aol.com)

Some excellent rants against this ... see Vernon Schryver's posts in
news.admin.net-abuse.email, in particular.
