Question : POP3 Resilience/Failover

I have two mail servers in my platform, running Sendmail and Dovecot on Red Hat Enterprise V3. The MX record provides for resilience within my mail domain, but I have a question on how resilience is provided for the mail databases.

If my prmary mail server fails incoming mail will route to the secondary server in the MX record, but how can I ensure that the users mail queue is up to date on the secondary mail server. Is there a function of Sendmail that can provide for this or do I need to use some form of clustering ?

I want to ensure that when my users access their mail via POP3, they don't lose acces to mail in their queue if the primary server is down and they are looking instead at the queue on the secondary server.

Thanks.

Answer : POP3 Resilience/Failover

As far as I know this not something sendmail does. You'll either need to write a script that can sync the mailboxes or mount the queue folder on some other server that both mail servers have access to.
