Re: Bug with lmtp_save_to_detail_mailbox

15 Mar 2023

      Documentation at https://doc.dovecot.org/configuration_manual/mail_location/

provides solution(s) for you:

SUBSCRIPTIONS

Specifies the filename used for storing subscriptions. The default is subscriptions. If you’re trying to avoid name collisions with a mailbox named subscriptions, then also consider setting MAILBOXDIR.

MAILBOXDIR

Specifies directory name under which all mailbox directories are stored. The default is empty unless otherwise described in the mailbox format pages.

Would either one be something you can consider? If you set MAILBOXDIR=mbox then your mailboxes go into ~/Maildir/mbox/

Config below.
I assumed the same at first, but deliveries for other "details" work 
without issues. Dovecot's 'subscriptions' file is present in the maildir 
which seems to conflict with the mailbox lookup.

Hi!
Can you provide your doveconf -n output, I think this might be a misconfiguration.
