RE: [PLUG] BIND zone oddity causing SendMail 451 Name server timeout errors?

--> What higher priority MX host? The zone files you posted earlier had only
--> one MX record for hostedexample.com, and that was the same as for
--> example.com - 10.1.1.53.
-->
--> Also, when you say "higher priority", do you mean a higher or lower
--> preference number? The one with a lower preference number would be tried
--> first.

hostedexample.com.zone file:
$TTL 86400
@       IN      SOA     ns3.example.com.  dnsadmin.example.com. (
                        2004073002 ; serial
                        3600 ; refresh
                        7200 ; retry
                        604800 ; expire
                        86400 ; ttl
                        )
        IN      NS      ns1.example.com.
        IN      NS      ns2.example.com.
        IN      NS      ns3.example.com.
@       IN      MX      10      email.example.com.
@       IN      MX      15      email.hostedexample.com.
; @       IN      MX      20      mailbag.voyagerhosting.net.
@       IN      A       10.1.1.22
email   IN      A       10.1.1.53
webmail IN      CNAME   email.hostedexample.com.
imap    IN      CNAME   email.hostedexample.com.
smtp    IN      CNAME   email.hostedexample.com.
www     IN      CNAME   hostedexample.com.

Where when I sent the third message in this thread the MX section was:
@       IN      MX      10      email.hostedexample.com.
@       IN      MX      20      mailbag.voyagerhosting.net.

--> The error message you quoted involved a name server timeout, so I

--> Ok, possibly silly question...  does gtcr.com have trouble sending to
--> example.com?

Can't say for sure but I think not.

--> Also, what sort of activity do your named logs show from gtcr.com?

Good question!
