Re: Bug with lmtp_save_to_detail_mailbox

15 Mar 2023

      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.
