Yes, very well.

No clue.

If you deliver a message to multiple recipients in the same store
[partition?] then the message gets stored once with multiple hard-links.
You have to have you MTA configured carefully so in the case of multiple
local recipients the message is delivered *once* via LMTP and not once
for ever local recipient.

See

and the references LMTP_README in the Postfix docs.

Option singleinstancestore in imapd.conf

[Lucas Zinato Carraro]

Hi,

i found this option in man imapd.conf


singleinstancestore: 1

If enabled, imapd, lmtpd and nntpd attempt to only write one copy of a
message per partition and create hard links, resulting in a
potentially large disk savings.



This option works ? This option is supported when using lmtpproxyd( murder )  ?
I dont see any difference when i enable this.
