OK thanks, I'll give it a whirl.

Yeah, unfortunatly I don't think it is possible..

The systems have 2 users on them (root & radar) and root gets some email (eg 
daily checks) and radar gets about zero (unless there is a problem with a 
cron job). We redirect both of these to us back at base.

The radar user sends some email (status reports from the radar for example) so 
if the network connection dies for a few days the outgoing emails start 
bouncing  back to radar@ which then attempt to get sent to the outside world.

So we don't have any problems when the network is operating properly but 
unfortunatly it can be rather variable in some places :)
