Hi Ankur,

I can remember something like using "FallbackSmartHost" in the sendmail configuration.

Hope I helped,

Sendmail's hp implementation is standard on HP-UX.

There should be no problem doing what you do on Linux on HP-UX.

The doc on the last post is available at http://www.sendmail.org

Starting and stopping sendmail is different on hp-ux

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

In sendmail.cf:

# fallback MX host. If specified, this host acts as a very low priority MX
# on every host. THis is intended to be used by sites with poor network
# connectivity.
O FallbackMXhost=backupmailservername


But that will only work if the one in DS is down...

DNS is better equiped to handle this via multiple MX records...basically - you create a "dummy" host - call it smtphost - and point it to:

smtphost.yourdomain.com. 3600 IN MX 20 realmailserver1.yourdomain.com.
smtphost.yourdomain.com. 3600 IN MX 10 realmailserver2.yourdomain.com.
