Just do pecandeluxe.com = pecandeluxe.com.smtp. What that does is tell SIMS that anything that comes in for the domain pecandeluxe.com, do nothing with it except attempt to forward it to the mail server for pecandeluxe.com. So SIMS will go out, check the MX record in the DNS for pecandeluxe.com and attempt to send to the primary mail server for that domain. Naturally, the first few attempts will probably fail because the primary is off line, but the idea is, combined with the long retry count, that before the max number of retries has been reached, the primary will come back online and accept the mail. The pecandeluxe.com = bigbrother.pecandeluxe.com.smtp isn't needed because that name transfer will be handled by the MX record in the DNS lookup. (and in fact, unless you ALSO have an MX record for bigbrother.pecandeluxe.com, it could cause the relay to fail). And don't forget, once you have the backup server up, you can do backup for multiple domains just by adding the correct domain.com = domain.com.smtp line into the router. My backup server is acting as backup for about a dozen domains right now. Those domains are spread across 3 different primary servers, but one backup server does them all. >Now, do I set up NO (zero, zip, nada) mail accounts on the secondary? >Aside from the default "Postmaster" account, that is. Correct. No accounts are needed on the backup server. You really don't even need the Postmaster account because in theory, the backup server will only be forwarding all mail it receives, so it should never attempt a local delivery to the postmaster anyway. (I personally have two accounts on my backup mail server, Postmaster, and my admin account. Both are there only so I can admin the server from remote. My admin one is the one I use for everything, but I have left the postmaster one on there from the initial setup just in case things get screwed up and I need it... I've never had mail delivered to either account as anything that hits that server gets relayed out to my primary for delivery). -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
