Who isn't a unix sysadmin these days? ;-)  

A resolution to keeping mail as individual packets and still having the 
SMTP server conserve connection overhead is to delay the que processing 
time. For example sendmail:  /sbin/sendmail -bd -q24h

Sets it to only process the queue once every 24 hrs. *shrug* If the SMTP 
server is dedicated to processing just the plant digest mailing list 
then effectively the problem is circumvented.  I would gess that perhaps 
one of the other issues to contend with is all the established users on 
the list not wanting to figure out how to filter incoming mail into a 
separate mail box.

I'll shut up now. I do have some plant problems I want help with in the 
near future. ;-)
