(ops, messed up the first send, again)

what do you think about replacing the deliver source in dovecot with
deliver from dovecot LDA? It would make it much easier to compile and
deploy dovecot LDA.

It would, but I don't want that, at least not currently. My plan is to merge them in some way at some point, but the Sieve code will always be kept out of the main Dovecot tarball as some kind of plugin.

The Sieve code is something I don't really want to touch myself, and I don't want it to be included in Dovecot's "1000 EUR for security hole" competition (or whatever it should be called).

Since the patch was a bit too large, I didn't accept your original mail to the list.
