With MMDF one would make one channel per host and, when the queue for that
host needs to be run, execute

	deliver -chosts-channel-name

However he is wanting to set up quite a lot of these.  Unfortunately the
channel tables in MMDF are allocated statically at compile time.  So either
he talks SCO into building him binaries with larger channel tables, or he
grabs the public sources off louie.udel.edu and recompiles himself.

The flag on sendmail is apparently something added in one of the commonly
available patched sendmails (IDA?).  It is done by

	/usr/lib/sendmail -Rhost.name

With either one on a dial up SLIP the server system hasn't a way to know
when the client system is attached.  Unless the client system is allowed to
do something to the server system to notify that it's there.  One way is
with rsh but that opens a security hole.  Another is with something like the
daemon I've written called `kickd'.

Kickd is started from inetd and thus can listen to any particular port you
desire.  When started it does getpeername() to find out the partner then
looks in a configuration file for actions to perform for that partner.  Very
simple.  So to solve the above the config file looks like

	davids.mmdf.com: /usr/lib/sendmail -Rdavids.mmdf.com

Or for an MMDF site

	client1.dircon.co.uk: /usr/mmdf/bin/deliver -cch-client1


I have been meaning to release this but it needs some cleanup, etc.

SUNOS 4.1.3 sendmail has a flag to allow mail to be flushed according
to a particular string in the to: filed. Demon use this I beleive to
flush SMTP mail when their dial up IP customers come on line.

I don't think it is standard sendmail tho. You might do worse than
grab the latset sendmail sources. Doubtless comp.mail.sendmail is
the right plcae to post this...
