Found the test mails - in /var/spool/mail/postfix

The problem would appear to be this (receiving domain & IP removed!)

============================================================================
Final-Recipient: rfc822; david@*******
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; host *******[***.***.***.***] said:
    550-Verification failed for <root at main.familyaldred.org.uk> 
550-unrouteable
    mail domain "main.familyaldred.org.uk" 550 Sender verify failed (in reply
    to RCPT TO command)
=============================================================================

As I read it, the mail is failing because the machine it's coming from 
(main.familyaldred.org.uk is its local name) hasn't any sort of public 
listing - so the receiving server can't verify it's legit.  (Interestingly, 
it does look as though mail from root made it off-site, even if it got no 
further).

Presumably the reason mail to some addresses (specifically gmail.com) did get 
through is that some servers are less picky!

Is there any easy way round this?
