[Dovecot] Duplicate Attachments....

[Charles Marcus]

Love Dovecot, many thanks for it!

But, I have a question regarding the storing of emails, with respect to 
efficiency...

Our business model (advertising industry) is such that our users 
exchange a lot of emails with attachments - most less than a megabyte, 
but some considerably larger. Consequently, I have been looking for a 
good, open source imap server that doesn't store multiple copies of the 
same attachment - but instead, stores a checksum, and whenever a message 
is stored with a duplicate attachment, the attachment is stored only 
once, and simply referenced by some kind of link to other emails.

This would *drastically* reduce the storage requirements for our company 
- imagine a message with a 10MB attachment, sent to 40 of our users, 
sometimes more than once. Now multiply this by 3 times per day, for 5 
years...

Are there any plans for Dovecot to support this type of storage in the 
future? Does this require the use of an SQL DB for storing the message 
components?
