You may be interested in this (transcript of SMTP chat to the UEA's mailgate5):
telnet mailgate5.uea.ac.uk 25 Trying 139.222.130.185... Connected to mailgate5.uea.ac.uk. Escape character is '^]'. 220 mailgate5.uea.ac.uk ESMTP Exim 4.50 Mon, 08 Oct 2007 11:10:40 +0100 EHLO 88-96-44-206.dsl.zen.co.uk 250-mailgate5.uea.ac.uk Hello 88-96-44-206.dsl.zen.co.uk [88.96.44.206] 250-SIZE 10485760 250-PIPELINING 250 HELP mail from: ted.harding@manchester.ac.uk 250 OK rcpt to: events@studios.uea.ac.uk 550 relay not permitted quit
Similar result with "rcpt to: richardlewis@fastmail.co.uk".
This is not definitive, since my 88-96-44-206.dsl.zen.co.uk is a personally-assigned fixed IP address for my ADSL service, and a lot of mailservers are configured to reject such connections unless it's for internal delivery (end even then may only accept from approved hosts).
But is suggests one of two possibilities:
A) The machine your exim connects from is not approved for SMTP transactions with UEA (as determined from its HELO of by reverse loopup) B) Your email destinations studios.uea.ac.uk and fastmail.co.uk are not within what UEa is prepared to route mail to (i.e. "relay").
I'm hoping that this may be a symptom of port 25 being inaccessible to outsiders as, when I try this from a host on the UEA network, I can get all the way to sending a message (which then gets bounced in the manner I described in my initial post). However, if I try it logged into a host elsewhere, I get the same result as you.
Thanks for having a look.
Cheers, Richard
