external mail server not working

[bmcclure]

We've got a customer who tried to change his MX record to point to an IP address. First there was a problem because it shows up as x.x.x.x.domain.com. instead of just the IP. I changed that manually and it still doesn't work. I've got an A record for mail.domain.com for their server and an MX record for their server. When you try to ping mail.domain.com it gives you our server's IP address, not his mail server. All mail gets returned as well.

What am I doing wrong?

Make sure the zone file looks like this:

@    14400   IN      SOA     ns1.domain.com. admin.domain.com. (
                        2003081201     ; serial, todays date + 1
                        7200           ; refresh, seconds
                        7200           ; retry, seconds
                        1209600        ; expire, seconds
                        3600 )         ; minimum, seconds

customer-domain.com. 14400 IN NS ns1.domain.com.
customer-domain.com. 14400 IN NS ns2.domain.com.
customer-domain.com. 14400 IN A  ip.ip.ip.ip

localhost.customer-domain.com.   14400    IN A       127.0.0.1

customer-domain.com. 14400 IN MX 0 mail.customer-domain.com.

mail    14400        IN A        ip.ip.ip.ip
www     14400        IN CNAME    customer-domain.com.
ftp     14400        IN A        ip.ip.ip.ip

Pay special attention to the periods after domain names & hostnames.

Thank you, this was figured out, somehow it kept showing up as ip.ip.ip.ip.domain. which obviously is wrong...

We ended up manually setting the MX and A records for mail to the IP and it works fine.

However, the customer was unable to set his MX record through CPanel, we had to do it manually. Why would this be? Thanks.
