I have postfix (2.0) delivering stuff here to up to 5000 users in a single
lmtp session (AND as a single message, too. We use it for site-wide
newsletters).  You just need to make sure all the limits (such as recipient
limit, per-transport limits, etc) agree.

Postfix will open one lmtp connection to cyrus, and use that for all it can
(that does mean to deliver a bunch of different mails to different
recipients). It will open a new lmtp connection only if all the current ones
are "busy" connections, AND you haven't told it not to (by limiting the
number of lmtp transports in  It will tear down the lmtp
connection only after it was idle for a while.
