I'm currently setting up a system, where mail is distributed via SMTP
across ethernet and dial-up SLIP, using smail. The problem is this:

Incoming mail is held in the spool directory waiting for delivery.
When smail 'runq' (same as /usr/lib/sendmail -q) is invoked, if the SLIP
link is not 'up', then smail will abort delivering the message, and reply to
the sender with 'Network unreachable'.

This seems reasonable, but what I would prefer to happen is for smail
to _defer_ the mail until the link *is* up. There is an option for this,
but this this is only implemented when the network/host is reachable
but not 'answering'; it doesn't cater for when there is no physical link
for IP packets.

I've scoured the man pages, and haven't found a way to avoid this.
It's not convenient to deliver mail only when the link is up, hence
before I start hacking the sources to change this, is there anything
obvious that I've missed? Or do I have to change to a better mail system?

Thanks,
Jon.
