Hello,

there is a nice feature in lmtp to save messages to user+foo@domain in
INBOX/foo Looks like that doesn't work as good if lda is used.

I have dovecot-2.2.13 mail_location = maildir:%h/ lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes *lmtp*_save_to_detail_mailbox = yes

messages to user+foo generate an error and are saved to INBOX not
matter if INBOX/foo exist or not: Dec 4 09:40:59 mail dovecot: lda(user@example.org): Debug: Effective
uid=10020, gid=10020, home=/var/mail/user@example.org/ Dec 4 09:40:59 mail dovecot: lda(user@example.org): Debug:

# doveadm user -u user@example.org userdb: user@example.org home : /var/mail/user@example.org/ quota_rule: *:bytes=1000000 master_user: user@example.org

# doveadm mailbox list -u user@example.org INBOX INBOX/bar

Possible, that *lda*_save_to_detail_mailbox is simply not implemented?

Thanks, Andreas
