email delivery fails

[robd]

Hello.
I'm using ISPConfig on FC4 (as a vm via xen). I have followed the Perfect Setup and all has worked fine e.g. web, sql, DNS etc

My users are able to login to POP mail OK too.

I have still a problem with Postfix. When I send an email to username@myserver.com to SMTP://mail.myserver.com postfix gives an error.

Dec 21 08:36:11 ns1 postfix/smtp[5466]: 5846A257AF: to=<web2_robdyke@85-234-137-244.poundhost.com>, orig_to=<rob@westhampstead.me.uk>, relay=none, delay=0, status=bounced (Host or domain name not found. Name service error for name=85-234-137-244.poundhost.com type=A: Host not found)

my server is ns1.networkassociations.org.uk
my server is on 85.234.137.244
my virtual domain is westhampstead.me.uk
my virtual server is on 85.234.137.248

Is this due to reverse DNS lookups?
(I can post much config / setup files if needed)

does anyone have some pointers for further investigation for me?

Please post the output of

hostname

and

hostname -f

. What's in /etc/postfix/main.cf?

[robd]

[root@ns1 ~]# hostname
ns1.networkassociations.org.uk
[root@ns1 ~]# hostname -f

ERROR: I couldn't find any MX records for neilnerva.org. If you want to receive E-mail on this domain, you should have MX record(s). Without any MX records, mailservers should attempt to deliver mail to the A record for neilnerva.org. I can't continue in a case like this, so I'm assuming you don't receive mail on this domain.

I notice this in the /var/log/maillog, this must be some kinda report or otherwise being delivered to root.

so delivery to mailbox's is working?

[robd]

I didn't have an /etc/hosts file.
I have created one......

[root@ns1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
85.234.137.244 ns1.networkassociations.org.uk ns1
85.234.137.248 ns2.networkassociations.org.uk ns2

And now my email send and receive is working!
