Hi Chris

host ntlworld.com brings up the following (which was not exactly what I 
was expecting):

  host ntlworld.com
ntlworld.com has address 212.250.162.12
ntlworld.com mail is handled by 5 alt1.aspmx.l.google.com.
ntlworld.com mail is handled by 5 alt2.aspmx.l.google.com.
ntlworld.com mail is handled by 10 aspmx2.googlemail.com.
ntlworld.com mail is handled by 10 aspmx3.googlemail.com.
ntlworld.com mail is handled by 1 aspmx.l.google.com.

I don't know if this has anything to do with my changing the nullmailer 
remotes file to use gmail - perhaps you can tell me.

I have now got a result (see below).  Thanks for your input.

Cheers,

Graham
