Of course! I'm sorry I'd completely forgotten that. I've confirmed by
telnet-ing to port 25 and writing an email directly that the Recieved

I think Mozilla Thunderbird 0.6 is generating the wrong hostname for use
in the HELO command - it used to always use the domain following the
in the email address you were sending from.
