Subject: Secondary mail server redux (no pun intended)

Hi,
I poured through a number of postings over the past year to find the correct
way to set up a secondary mail server. But it does not seem to be right yet,
and I hope someone on  the list can point out the obvious mistake I made
somewhere along the line (which is why am so verbose with my setup details,
given below)

I am hosting multiple domains as well as having multiple servers, and that
may muddle the picture somewhat.
Anyway, I thought I had it figured out until I sent myself some mail today
when the primary mail server was acting flakey, and I got this bounce
message:

------------------------------------------------------------
Failed to deliver your message to kevin@manuex.com.smtp:
SMTP: DNS Routing Loop
The Domain Name System record for 'manuex.com.smtp'
points back to 'mail2.manuex.com'.
------------------------------------------------------------
(rest of message, including header info, at end of this post, if it helps)


So here is what I have set up DNS and SIMS wise: Two backup mail servers.
One on a remote network, and one right next door to the main server. DNS as
follows:

--------------------------------------------------------------
DNS for manuex.com
--------------------------------------------------------------
manuex.com        A      66.92.77.165
mail.manuex.com   CNAME  manuex.com
mail2.manuex.com  A      65.84.187.144
mail3.manuex.com  A      66.92.77.164

manuex.com  MX 10  mail.manuex.com
manuex.com  MX 20  mail2.manuex.com
manuex.com  MX 20  mail3.manuex.com
--------------------------------------------------------------
--------------------------------------------------------------
DNS for themanufacturingexchange.com
--------------------------------------------------------------
themanufacturingexchange.com  MX 10  mail.manuex.com
themanufacturingexchange.com  MX 20  mail2.manuex.com
themanufacturingexchange.com  MX 30  mail3.manuex.com
--------------------------------------------------------------

All three mail servers have SIMS set up. I'd be happy to just get two
working. Here is how "mail" and "mail2" are set up:

mail.manuex.com has the works:
--------------------------------------------------------------
Server->General... :
  Internet Domain Name: manuex.com
SMTP -> Service Settings:
  Sending Options: Direct to recipients
  Anto-spam: verify return path
Server -> Router... :
  ; Map all hosts to top level domains
  ;
  *.themanufacturingexchange.com = manuex.com
  *.manuex.com                   = manuex.com
  *.kohrt.net                    = manuex.com
  *.planetbuildit.com            = manuex.com
  kohrt.net                      = manuex.com
  planetbuildit.com              = manuex.com
  manuex.com                     = manuex.com
  ;
  ; map kohrt.net & tme accounts to the same local account name
  ;
  <*@kohrt.net> = *
  <*@themanufacturingexchange.com> = *
--------------------------------------------------------------


mail2.manuex.com should be a backup server for both
manuex.com and themanufacturignexchange.com
--------------------------------------------------------------
Server->General... :
  Internet Domain Name: mail2.manuex.com
SMTP -> Service Settings:
  Sending Options: Direct to recipients
  Anto-spam: verify return path
Server -> Router... :
  *.themanufacturingexchange.com = manuex.com
  *.manuex.com = manuex.com
  manuex.com = manuex.com.smtp
--------------------------------------------------------------


I actually wrote up (w/screen shots) instructions for my secondary mail
server here
http://www.maxmanufacturing.com/admin/help/SIMS/BackUpServer/
but I have since changed the Router.. info, and I'm afraid the extra
"*.manuex.com" may have been a "bad thing".

mail3.manuex.com only has the following routing:
--------------------------------------------------------------
  *.themanufacturingexchange.com = manuex.com
  manuex.com = manuex.com.smtp
--------------------------------------------------------------

but even it seems to be running amok. Filtering the logs for one message in
particular that it handled, I get (edited for 80 columns):
--------------------------------------------------------------

--------------------------------------------------------------

Has mail3.manuex.com just thrown away an email?

Can anyone shed some light here? I thought I knew what I was doing, and I
had in fact been running a single SIMS server happily for over a year. Now I
suddenly feel like the Router uses VooDoo logic and the Log files are
written in machine language (though you must admit, both could use some more
extensive documentation and/or reference material--perhaps I can write
something if I ever get it all figured out)

Thanks in advance
