I have a grotty DNS hack to do something like this for my home gateway
machine which works using a cablemodem most of the time, but falls
back to dialup when necessary. To do this, I have defined a ".mail"
zone and configured all mail to use "wibble.mail" as a smart host.
# ROUTERS
#
# Send all mail to a smarthost
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "*.mossbank.org.uk $domain bydns; \
* wibble.mail bydns_mx"
"mossbank.org.uk" is the internal house domain, BTW.
I then have a script in the ppp setup/shutdown directories that will
move the appropriate zone file for .mail into place when network
interfaces change. That way I can send mail regardless of network
state and even queued mail will be sent to the right smarthost.
Zone example:
@ IN SOA lump.mossbank.org.uk. postmaster.mossbank.org.uk. (
1 ; Serial (yymmddxx)
10800 ; Refresh 3 hours
3600 ; Retry 1 hour
3600000 ; Expire 1000 hours
86400 ) ; Minimum 24 hours
@ IN NS lump.mossbank.org.uk.
wibble IN A 127.0.0.1
IN MX 1 smtp.ntlworld.com.
Hope this helps...

Getting a SCSI chain working is perfectly simple if you remember that there
must be exactly three terminations: one on one end of the cable, one on the
far end, and the goat, terminated over the SCSI chain with a silver-handled
knife whilst burning *black* candles. --- Anthony DeBoer
