Hi list, many moons ago I asked about preserving hardlink between identical messages when pigeonhole (for sieve filtering) was used.
The reply was that, while hardlink worked well for non-filtered messages, using pigeonhole broke the hardlink (ie: some message-specific data was appended to the actual mail file). Here you can find the original thread: https://dovecot.org/pipermail/dovecot/2015-November/102579.html
I would ask the same things today: is dovecot+pigeonhole capable of storing the same incoming message, sent to multiple rcpt or to a group/alias expanding in multiple recipients, as a single hardlink?
Note: I know about SIS, but it has some important drawback and I would avoid using it.
Thanks.
