Thanks for the suggestion, but when Postfix rejects a message because
it's too big, Postfix generates the bounce; it doesn't wait to deliver
it via LMTP and then complain that LMTP gave a bad return value (which
is nonsensical, if Postfix is rejecting the message).  Re-read the
error message; note that Postfix is merely reporting the error it got
from LMTPD.

For the message in question, here's the Postfix queue manager
receiving it:

Jun 25 13:58:47 vostok postfix/qmgr[9323]: 58A6373D6F6:
from=<sender@xxxxxxxxxxx>, size=16243093, nrcpt=1 (queue active)

>From main.cf:

message_size_limit = 20480000

16243093 < 20480000

I can also see the message being processed by the cleanup daemon,
which is the daemon that would be bouncing the messages if they were
too large.

This remains a problem with LMTPD.
