using mailboxes.db replicated copy for lmtpdproxyd

[Andrey B Semakin]

Hello all .   Is it possible for lmtpdproxyd to use mailboxes.db local replicated copy (as for proxyd) instead of using mupdate master server directly?   Our server is heavy loaded (more than 40 messages/sec and number of mailboxes more than 800.000). We are using cyrus-imapd-2.2.3.   Andrey Semakin
