Patrice, You should be able to do something like this in your transports file during your migration: knownuser1@xxxxxxxxxxx lmtp:unix:/var/run/cyrus/socket/lmtp knownuser2@xxxxxxxxxxx lmtp:unix:/var/run/cyrus/socket/lmtp knownuser3@xxxxxxxxxxx lmtp:unix:/var/run/cyrus/socket/lmtp example.com smtp:[ip.address.of.exchange] see the man page for postfix's 'transport' for more details. You might also be able to make use of an ldap mailbox_transport_map to do the same thing: http://www.postfix.org/postconf.5.html#mailbox_transport_maps - Dan ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
