Interesting. I thought relaying via your ISP's mail host was
practically compulsory for dialup accounts. I even know of ISPs for
which I think that's the only way to send email. Does anyone know if
this is a realistic view of the world, or am I sadly deluded by
happening to have encountered a few unusual ISPs?
