SMTP shouldn't be a problem, no real state to be maintained
between connections.

POP3 may be a problem if you don't have some sort of shared
spool or replication between the pop3 servers.  What's your POP3
server?

- and then set Outlook (I use version 2003) to
- use pop3.JAMMConsulting.com and smtp.JAMMConsulting.com
- as its incoming and outgoing server, will Outlook
- whichever IP address is available if one of them
- is down?

I dunno, is Outlook smart enough to try more than one IP address
in a result set?

If it's smart enough to try all the addresses in a DNS result
set, then it should work.  If not, well, it's broken.. (but
there are my networking apps that are broken in that fashion,
and not just on Windows.)
