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. -jf
