There are a number of free options: 1) MS SMTP server 2) XMAIL - http://www.xmailserver.org/ 3) Len's IMGATE W> I've gone through the knowledge base and found some things, but to W> be frank, I'm a bit confused by what I'm supposed to do. It only seems confusing. Just follow the directions exactly as written and it will work just fine.

For any backup mail server: 1) set up your backup mail server 2) add an A record for the address 3) add an MX for the A record at a lower priority than your primary Now for IMAIL - 4) add an entry in the HOSTS file on the secondary server pointing to the IP address of the primary, e.g.: 123.123.123.123 mail.example.com 5) add the primary's IP into your range of addresses that can relay *** BIG WARNING: DO NOT put the secondary server's IP address in the addresses list of the primary or you will become an open relay. For MS SMTP - 4) add a REMOTE domain (for each alias too) and set the remote domain to forward mail to the primary 5) remember to control relaying on this thing - it will get you in trouble if you don't XMAIL - refer to the docs - not difficult - great mail server W> other thing, what would be the cons of changing the secondary W> server's SMTP service to a different port then 25 since we won't be W> using it to do any relaying? No, you can't do that. If your primary goes down the rest of the internet has to be able to find the secondary so it needs to answer on 25.
