No ,and it's difficult on several levels. if a mail server is down, spool up the mail on your backup MX box and deliver them when the mail server is back up.
If it's really important, your mail will reside on an external RAID box. You can either implement HA ($$$$) or just move the RAID box to another machine and run a script to make it the backup server (spare interface becomes the POP server interface, etc). I've done the latter at an ISP long ago. It was *never* used. It was always easier to just fix the 'dead' machine (swap a power supply, whatever). My experience is that machines rarely actually die, hard.
