Hi Tim,

Even if if supports authentication, I'd doubt very much that they'd
allow access through a non-talktalk line - that's pretty standard
practice to prevent use as a spam relay.

Ah, is it?  I thought auth., or at least secure auth. where credentials
aren't passed as plain text, wsa there to permit this kind of thing.
You're right, it does seem many ISPs don't provide it though.  I see
plus.net does, but then I'm found them to be a bit better than average
in the past.

Talktalk is very consumer-targeted. It would only require a credentials leak from one of their hundreds of thousands of customers and they'd have an open relay on their hands.

I've stuck the notes on the Wiki at
