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?
I thought I'd just mention aradis which can extract and replace the attachment. The attachment itself can then be delivered to a webserver, the filesystem or a custom script.

(I am the author of aradis and we use it mainly for mailinglists.:-)
Cheers, Jens
