OK, I've been banging my head on why my procmail setup for virtual users is no
longer working (difficult to test, since enabling it breaks live user's mail).
There are only a few virtual users who have any sort of filters in place anyway
(the heavy procmail users are local, not virtual), and they are fairly simple,
so I think I can recreate them with sieve.
I think I have everything I need for sieve to work, but now what?
The first thing I want to do is have sieve process recipient_delimiter into a
separate mailbox (creating it, if needed). Googling just for example sieve
scripts comes up empty (well, directing to the dovecot wiki which at least on
the links that come up, does not have sample scripts).
so, foo+...@example.com will go into foo's mailstore in the folder .bar/new/

Which I still don't understand.
recipient_delimiter = + is the default, so I shouldn't need to set it in my
confs, I just need to setup a sieve recipe (is that what it is called? script?)
that will process these messages, right? What would that look like?
I have to setup the SQL users so that LMTP or LDA is used for deliver, but I
want that to apply only to the sql users. Something like this, maybe?
This particular step is done in your MTA. So, how do you deliver your
messages from the MTA into the mail storage of the user? If you want to
use procmail for system users and Dovecot's LDA/LMTP for virtual users,
you need to configure a separation _there_ already. The MTA decides with
LDA to use: procmail vs. Dovecot.
My reply above applies to the branch, when the MTA uses Dovecot LDA to
deliver messages (to virtual users). Then use the -m option of the Dovecot
LDA, no need for a Sieve script. See http://wiki2.dovecot.org/LDA/Postfix
If you use Dovecot's LMTP service, set lmtp_save_to_detail_mailbox = yes,
no need for Sieve script either. However, Sieve can override this default
mailbox with fileinto, actually both variants just replace the default
mailbox (aka INBOX).
If you want to use a Sieve script, you need to get the "subaddress" of the
envelope recipient address. I've never done this.
See http://wiki2.dovecot.org/Pigeonhole/Sieve/Examples 2nd example in
section "Plus Addressed mail filtering", however some MTA do not pass
envelope information to Dovecot LDA, LMTP would be required then. See
remark below that example, too.

}
I'm sure that protoco_lda isn't the right syntax though.
If I set sieve=/var/sieve/%u.sieve as above would users still be able to use
sieve-manage to manage their own sieve files? And what MUAs support this?
If I left that out, do I put ~/.dovecot.sieve in with the other mailboxes and
{cur,new,tmp} and the index files, or will there be issues? If I put a
dovecot.sieve file there will it just be seen, processed, and work?
(SQL user's $HOME is their maildir)
