MX records

Hi list,
I am in a bind trying to figure out what I did wrong with my zone files. I
have 2 servers. One runs bind, post.office and a bunch of web sites. I now
have a couple servers and am putting web sites on there. However, something
in my DNS records is wrong; Email sent from non-local domains to our domains
that have web sites on the 2nd server bounce with this reason: 5.7.1
Unable to relay for someone at somebody.com.
Here is a mock up zone file for primary somebody.com. Do you see anything
wrong with the MX records that would cause this?
;
@ IN SOA ns1.myfirstserver.com. hostmaster.myfirstserver.com. (
2000122001 ; serial number
43200 ; refresh every 12 hours
7200 ; retry after 2 hours
1209600 ; expire after 2 weeks
172800) ; default ttl is 2 days
;
IN NS ns1.myfirstserver.com.
;
localhost IN A 127.0.0.1
;
; Other Name servers
@ IN NS ns2.someoneelsesserver.com.
;Mail eXchange records
pop IN A 1.2.3.123
IN MX 10 pop.somebody.com.
smtp IN A 1.2.3.123 ;SMTP server
mail IN cname smtp.safepages.com. ;external SMTP server for
dialup clients
www IN A 1.2.3.4 ;web site on my other second server
@ IN A 1.2.3.4 ;web site
ftp IN cname www ;ftp site
This is weird: if I change the web site address in the zone file from
1.2.3.4 to an IP on the same system as post.office and bind, people can send
email to the domain.
Thank you very much for your help,
David Gamache
