[nycbug-talk] BIND and MX records

[Rodrique Heron]

Hi Guys,

I inherited a bind server and I'm trying to clean it up, I noticed that 
allot of the host records have MX entries like this:

mailstore01      A       192.168.2.1
                        MX      10 mx1
                        MX      12 mx2
                        MX      14 mx3

 From what I understand, this forces mail sent to host.domain to always 
go through one of the MX servers. But is this necessary for the mail 
store ? Are their any known side effects ? I am trying to ascertain if 
it's causing an occasional problem I'm having with mail delivered to our 
domain bouncing with the following error:

Maximum hop count exceeded. Message probably in a routing loop.

Thanks
