Since switching to lmtp in dovecot, mail to user+mailboix@example.com does not get saved in ‘.mailbox’ as it did with LDA, instead it gets saved into the INBOX. If it matters, these are users who do NOT have a ~/.active_sieve file. I could understand (though it would bene a bit annoying) if the save overrode this mechanism.

I did add lmtp_save_to_detail_mailbox = yes in the protocol lmtp block

protocol lmtp { postmaster_address = postmaster@covisp.net # required mail_plugins = quota sieve info_log_path = /var/log/dovecot-lmtp.log lmtp_save_to_detail_mailbox = yes }

This is the error I am getting when sending to luser+covisp@covisp.net

lmtp(luser@covisp.net)<91193><EqkiJV70A105ZAEAIdGjjQ>: Error: sieve: msgid=<A3ED963A-97FB-4A1F-9F09-45F2AEA96CF6@kreme.com>: failed to store into mailbox 'covisp': Mailbox doesn't exist: covisp

cat /usr/lib/dovecot/sieve/default.sieve [13:32] [/var/log]

require "fileinto"; if header :contains "X-spam-flag" "YES" { fileinto "Junk"; }

(This file hasn’t changed in a year, so it worked fine with the lda instead of the lmtp setup. I mean, I can probably just write a sieve to do it. Let me think…

if header :regex "to" “+(.*)@" { fileinto :create “${1}"; stop; }

Seems like it should work. Should I add this to default.sieve?
