Hmm, not sure about the double error, but the "502" error you got means
that it doesn't implement ESMTP, at which point the client SMTP server
should either send HELO or QUIT. Exim sends HELO as it should.

Thanks for that, that's a great suggestion and seems like it might solve
some of these problems, I'll give it a go and report back to the list if I
have any success. Of course, I'd still like to find out exactly why this
works sometimes but not others, so I'll probably continue investigating :)

Cheers,
