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 [EMAIL PROTECTED]: 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): -------------------------------------------------------------- 16:56:30 2 SMTP-012(smtp5.weblications.com) {S.0000024925} received, 889 bytes 16:56:30 4 SMTP-012(smtp5.weblications.com) Sending 250 S.0000024925 message accepted for delivery\r\n 16:56:30 2 SYSTEM [S.0000024925] <[EMAIL PROTECTED]> 1+0 From:[EMAIL PROTECTED] 16:56:30 4 SMTP [S.0000024925] is enqueued 16:56:30 4 SMTP Line 14 created for manuex.com.smtp, [S.0000024925] 16:56:30 4 SMTP [S.0000024925] queued to line 14(0/1). 1 routes 16:56:34 3 SMTP [S.0000024925] dequeueing 16:56:34 1 SYSTEM(SMTP) [S.0000024925] failed on (manuex.com.smtp)alexis.

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 --Kevin [EMAIL PROTECTED] -------------------------------------------------------------- Entire bounce message, which included the original header info -------------------------------------------------------------- Failed to deliver your message to [EMAIL PROTECTED]: SMTP: DNS Routing Loop The Domain Name System record for 'manuex.com.smtp' points back to 'mail2.manuex.com'.
