Hello, I have my own domain, let's say: myrealname.org. I already set up a mail server (mail.myrealname.org) and MX record for that domain, with MX = 10 and it works just fine. What I need help is with the following. I want to setup a backup mail server with MX = 20, so in case the main mail server is down, the backup mail server will collect the incoming mail. The backup mail server, let's call it myothermachine.org is on another network. How do I set up the backup mail server (using sendmail) to do the following (1). If mail.myrealname.org is down, collect the incoming mail for that domain, and keep trying to relay the incoming to the mail.myrealname.org. But the backup mail server should _never_ inform the mail sender that mail.myrealname.org (I've played around with this a bit, and by default the backup mail server sends a respond back to the mail sender saying basically that the main mailserver is down, and it keeps trying to relay. I don't think the sender needs to know that). (2). While doing (1) and keep trying to relay to mail.myrealname.org, I want the backup mail server to also send a copy of all incoming mails to yet another account, say "myname@xxxxxxxxx". So in the case that I am away and cannot bring the main mail server up, I still can get to my emails. When the main mail server is back, then the backup mail server should flush all the mails that it stores to the main mail server. Any help / pointer on how do this ? Thank you in advance.
