LMTP hackings

For those that might be interested, I've tared up another "rev" of
the lmtp-19990427 patch. The URL is:

http://ftp.utdallas.edu/pub/staff/amos/postfix/lmtp-19990427-05.tar.gz

My previous hackings dropped the cached connections support as I was
learning how stuff works. I've added the cached connections back
in, and we've been using it on our systems for a couple of weeks.

You may want to fiddle with the number of instances of lmtp you have
as well as the max_use setting in main.cf. While I suspect it would
not be wise to pump up max_use too high, I've been running with it
at 200 and it seems to be okay. I've also got the number of lmtp
sessions currently set at 3.

To install, cd into the Postfix source dir and untar the file above,
then apply the following two patches:

patch -p0 < lmtp/makefile-patch
patch -p0 < lmtp/global-patch

These diffs were done against postfix-19991231-pl02.

Currently, this version of lmtp supports both pipes and inet
connections. This will very likely change in some subsequent
rendition. Instead, it will only use either UNIX domain sockets or
inet sockets. An additional process will be responsible for running
deliver in LMTP mode. This is so that things are better
compartmentalized into the appropriate pieces for the respective
task. The current offering is simply made as an interim solution.
So if you use this, realize that the configuration of the various
pieces will be changing.
