Exim; local/Internet delivery

[Christopher Clark <chris@maltwhiskey.demon.co.uk>]

There has been a lot of traffic about Exim, so I apologise if this is old hat.
I use sendmail (with the 'expensive' option) to deliver local mail immediately
and queue Internet mail until my cron job connects to my dial up ISP and then
does a sendmail -q
Can you do the same with Exim?
Incidentally the reason I chose sendmail was that the exim documentation
suggested it wouldn't work with nfs mounted /var/spool/mail (and it didn't).
has that changed?
