[IMail Forum] IMail Server Backup

[William Raby]

We are currently thinking about putting a backup server in another location to spool any email received during downtimes at our mail location.   I understand how DNS records need to be configured, but my question is how do I actually configure IMAIL for this.  Do I need to replicate all of the domains and users on the secondary server or does it just spool any email it received until the primary server comes back online and then all of the filtering and email rejections are done from there?   Thanks in Advance, Bill
