Ah, then Timo's reply was right. He suggested you do the lmtp-deliveries
to the same server that you would send you imap-user to.  You can do this
trough dovecot director and lmtp-proxying.

So instead of:

	lmtp:unix:private/dovecot-lmtp

you should use:

	lmtp:tcp:1.2.3.4:24

where 1.2.3.4 would be the Dovecot LMTP proxy that proxies to the same
machine as you would use for imap for this particular recipient.
