Hello to everyone! Ooops, we are using SIS, guess the solution for a similar optimization will be a native deduplicated filesystem.
A block level de-duplicating filesystem can only deduplicate data that is aligned to block boundaries. E-mail attachments tend to move around in to a different alignment in each copy stored into a different mailbox. Unless the storage format is designed to split off the attachments into files there is not much to be gained by block level dedup. So for the foreseeable future I'll have to stay off Dovecot 3.x or add four to five times more storage to both my IMAP servers since my users love to send big documents to multiple recipients.
Is this an attempt to figuring out the pain tolerance of existing users before they fork the project or pay up the Danegeld?
SIS won't be available even if you paid up the Danegeld. You can use mail_attachment_fs with posix driver.
