Is it possible to have a secondary MX host that will just queue incoming
messsages and relay them back to the main mailserver when it becomes
available? Here's the scenario:
Box 1:
Hardware {
AMD K62-500mhz
256megs RAM
two 15Gig ATA disks
}
Purpose: primary mail server/radiusd
Software: Livingston radiusd, compiled on machine; for machine
Sendmail <not sure ver -am not at location right now)
cucipop 1.3
FreeBSD 4.0-STABLE-20000602
Box 2:
Hardware {
AMD K62-500mhz
128megs RAM
one 13Gig ATA disk
}
Purpose: Secondary radiusd/mail server
Software: Livingston radiusd, compiled on machine; for machine
Sendmail <not sure ver -am not at location right now)
cucipop 1.3
FreeBSD 4.0-STABLE-20000602
Essentially, when box one becomes too overloaded, and/or is not active,
(eg during a reboot), I want box 2 to take over for it.
The radius software pulls it's users/configuration from an NFS server,
both machines mount the same volume, and have read-only access to it;
write access to their logging directories (also mounted over nfs). The
machines themselves are connected on a small private subnet to the NFS
server, and directly to internet via ethernet, (tied to router/switch
obviously). Essentially, radius should not be a problem. The problem I'm
seeing is mail; if I mounted /var/mail over nfs to both machines users
would be able to access either to send or receive email no? (assuming
both machines have the same user/passwd of course -they do) Personally I
don't like this idea though; I'd rather the mailservers used their own
drives. I know there's got to be a way of doing this, just not sure how
to go about it.
Any suggestions, comments, concerns, redirects or otherwise are more
than welcomed.
