If the recipients are sent one at a time with duplicate DATA commands, there are treated as distinct messages.That is the problem, postfix default local transport does only one at a time, that breaks single instance storage. We had to redefine it to: local_transport = lmtp:unix:/lmtp/lmtp Please read about the consequences in postconf manual. Hope that helps Michael is right on the money here. I hadn't noticed that you had defined mailbox_transport rather than local_transport. This is our typical postfix configuration in support of singleinstancestore: The warnings Michael was referring to are covered in http://www.postfix.org/LOCAL_RECIPIENT_README.htmllocal_recipient_maps = ldap:/etc/postfix/local_recipient_map.ldap, ldap:/etc/postfix/alias_map.ldap local_transport = lmtp:unix:/mailstore/lib/imap/socket/lmtp local_destination_recipient_limit = 300 local_destination_concurrency_limit = 5 Specifically, if one overrides the local_transport, it's important that one also properly qualifies all local_recipients (quoting): In our case we most often use LDAP for this, as shown above, but whatever DB is best for you, etc. Cheers, -nic -- Nic Bernstein nic@xxxxxxxxxxx Onlight llc. www.onlight.com 219 N.
