The Dovecot wiki [1] doesn't list either Exim, Postfix or anything else as supporting the dbox. I did some searching in the Exim archives and have found only one message mentioning dbox, sdbox or mdbox. [2] I think an RFC would go a long way towards getting the format supported. Has Timo, or anyone else, considered submitting an RFC to the IETF?
No, and I don't want it to happen anytime in near future. The dbox format is highly Dovecot-specific, because it relies on Dovecot's index files. These index files are still changing and I'm not sure if they will ever be fully finished. I don't want any other software to even attempt to implement the same functionality.
My question was how are we going to use it if Exim doesn't support it.
As others said, use LMTP or dovecot-lda with Sieve filtering.
