wierd mx record

[dbotham at edeltacom.com]

Dale,

If the entries appear as you show them below in the zone file then each of
the MX records is for a different email address...

For instance:

The first one is for mail addressed to <user>@NS1.<$origin>.

The second is for mail addressed to <user>@pop.<$origin>.


and so on.  While this configuration is not typical, there is nothing wrong
with it.  However, I doubt it does what your customer thinks it does...


Thanks,

Dave...

I have a customer that hosts there own DNS. When I went out to their
site to help them with an issue. After looking at their DNS, I was
amazed to find the following as the mx portion of their DNS.
I have inserted the words "ip address" as the ip address instead of
putting theirs.



NS1   IN     A     ipaddress
      IN     MX     10 mail.domain.net.
pop   IN     A     ipaddress
      IN     MX     10 mail.domain.net.
mail  IN     A     ipaddress
      IN     MX     10 po.domain.net.
po    IN     A     ipaddress
      IN     MX     10 mail2.domain.net.


I have never seen entries such as these. Any idea why it would have
been set up with all the same weights? I am assuming DNS would just
ignore anything past the first one. Is this a correct assumuption?
Thanks for any help,

Dale Toney
