Having multiple mail spool servers is not very recommended unless there's
a very urgent need. The main issue is with file locking. If you do a
search for "file locking sendmail" on google, you'll see why. We at EE
department have 2 mail spool servers connected together through a SCSI
interface with the spool disks in the middle. The 2 mail servers
communicate with each other through heartbeat and if the primary mail
server goes down, the backup server takes over. The heartbeat solution is
for redundancy, if you are looking for load balancing then you should
consider having mail gateway servers that queue mail.
