What surprises me is that hard-linking identical messages saves so
much space, yet nobody seems to asking/using such feature.
So, either a) few cares about saving space or b) few are using the
pigeonhole plugin. And both a) and b) seems unlikely...
Or
c) we see nearly no truly identical messages.
Well, sure, this is another possibility.
However, on all mailserver which I manage, a significant portion of
total emails are messages sent to groups/lists rather than single
recipient. Cyrus and other proprietary mailservers (eg: CommuniGate Pro)
use unix shared storage (aka hardlink) to avoid copying the message to
multiple inboxes. This is especially valuable when a) large groups
exists or b) a large message is sent to groups/lists.
Please also note that, when not using Pigeonhole, Dovecot *does* use
hardlink for messages sent to multiple recipients and/or groups. It is
only when Pigeonhole is active that the hardlinking does not happen.
Thanks.
