Exchange 2000 will refuse to relay mail to another domain, regardless of MX records. Unless you specifically instruct it to do so by defining an address space for that target domain and check the option "Allow relaying to this domain". To do all that, you need to start by creating an SMTP connector.

Every unix MTA I've worked with has been intelligent enough to realize when there is a higher priority MX for the domain, and to automatically deliver mail to that machine. This, of course, assumes that the MTA is not configured as the final destination for that domain's mail, just as a relay. Does Exchange not work this way?

Yeah, point the secondary MX at the abc.com's Exchange 2000 server. But you will have to do other tricks to make it work so that abc.com's Exchange 2000 server would accept mail for fgh.com and then actually reroute it to fgh.com's Exchange 2000 server. But since the latter is down, then mail is going to sit in a retry queue... You want to make sure that it could hold it longer than 2-3 days, until fgh.com's Exchange 2000 server is up again and can accept mail. This is almost like ETRN. Well, you can actually set things up to be ETRN. You will need to create an additional SMTP connector on abc.com with address space for fgh.com with cost = 1, and select the option that would allow to relay mail to fgh.com. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Phillip Stafford Sent: Thursday, April 01, 2004 2:15 PM To: Exchange Discussions Subject: RE: Backup MX Two domains, meaning that the exchange server on one domain (such as abc.com) would also utilize their Exchange 2k server to provide backup mail service to domain fgh.com in the event that fgh.com's exchange server goes down. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fyodorov, Andrey FTL Sent: Thursday, April 01, 2004 1:48 PM To: Exchange Discussions Subject: RE: Backup MX Why are there two domains? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Phillip Stafford Sent: Thursday, April 01, 2004 1:37 PM To: Exchange Discussions Subject: Backup MX Anyone know the proper way for setting up 1 Exchange server to be another one's backup server? I have been searching high and low and have come upon several different supposed methods. None seem to work fully. Right now, what I have done is configured external DNS for domain B to have MX 20 (primary is MX 10) point to domain a. On Exchange server B, I have setup an SMTP connector with the domain name, the IP address for that exchange server listed in the smart host field, have configured within their to allow relaying through my server, etc. However, when we tried a test of this backup MX, I could not visibly tell whether my server was acting as a backup. I was looking at the SMTP queues and I couldn't find any messages listed for that connector even though I had been sending email to domain B and had not received any NDRs. Any help is appreciated. Thanks. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
