Hi!
For automated failover, there are kinda tricky solutions available.
for manual failover, simply bind the other address as an alias on the
same physical interface on one card, or use a /32 subnet mask on the
second NIC.
BTW: in case of mailers, you could also solve the problem with different
mx records:
>host yahoo.de
yahoo.de has address 217.12.3.11
yahoo.de mail is handled (pri=5) by mx4.mail.yahoo.com
yahoo.de mail is handled (pri=1) by mx1.mail.yahoo.com
yahoo.de mail is handled (pri=1) by mx2.mail.yahoo.com
So you could simply specify some fallback mailer that picks it up, no
fiddling with different IP...
