>How do I get the secondary to pick up the mail when the primary is down?
If you setup the MX records correctly, this should be done by the sending server. It will look at the MX records and try sending to the server with the lowest value, if it doesn't accept the mail, it will move up the MX records in order of the value until a server takes the mail (or it runs out of records to try). So if setup correctly, it should basically be transparent to you. >How do I get the clients to obtain their mail from the secondary when the >primary is down? They don't. They get their mail from the primary. The secondary just acts as a mail relay to the primary. So when the secondary takes the mail, it just tries repeatedly to send the mail on to the primary with the plan that the primary will come back online and accept the mail before the max number of attempts is reached. So while the primary is down, your clients can't check their mail. If you need redunancy like that, then I can't help you with setting up SIMS for that. So to set it up, the first step is to assign the MX records. You would set your primary server with a lower value than your secondary. So the MX record should be something like this primary.domain.com MX 10 ###.###.###.### secondary.domain.com MX 30 ###.###.###.### Then in the seconday server's router put the following doamin.com = domain.com.smtp And set the number of retries (in the SMTP settings) to something high (figure on your duration to retry * number of retries will tell you how long it will continue to attempt to send the mail before giving up... my old ISP was REALLY unreliable so I have mine set to 30 minutes between retries with 250 attempts before stopping, so it will retry for 125 hours or roughly 5 days before giving up). -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
