BT are good at that. AOL does (did?) it too. I think Orange (or whatever they are called) do the same. It would not surprise me if others move to the same thing eventually. They claim it's to stop SPAM being sent, but who knows.. Basically they intercept outgoing port 25 connections and force them to their own servers regardless of the destination. If you have your own (remote) SMTP server, then the usual way round it is to use the submission port (Which arguably you should be using anyway), so set your MUA to use port 587 rather than port 25 when connecting to the remote service. Although I'm sure that one BT, etc. get wind of this, they'll block that too. > I tried to get out of the contract by claiming it was not fit for > purpose, but they said their T&C's ruled out business use and own domain > name = business use. > > After much much argument and several shifts up the chain of command I > got a manager who told me, on sort of semi confidential basis, that he > could let me have a mail server address that "would make it look as if > the mail had come from my own address".

Who knows, but BT do have a mechanism whereby you can register your own additional email addresses to use for outgoing email - maybe they don't extend that to their resellers. Odd that the port office went to BT retail for this thing. I remember a press release from BT at the time saying that the post office should stick to what it does best, and leave Internet to BT ...
