Using dovecot-shared for an shared index not working
by Achim Gottinger 18 Feb '22

18 Feb '22

Hello I'm in the process to migrate our mail server from version 2.2.13 with maildirs to 2.3.13 with sdbox. On the old server if we wanted an common index for the seen flag on shared folders we created an file called dovecot-shared in the mail_location folder and the mailbox folders. This does not work on the new server for all shared mailboxes the seen flag is stored per user. The log file shows this if the seen flag is changed Feb 18 13:24:15 SERVER dovecot[18887]: imap(USER)<18978>&… [View More]lt;51HhlUnYeOfAwAx3>: Debug: imapsieve: mailbox shared/info: FLAG event (changed flags: \Seen) The dovecot-acl file for the shared/info/INBOX folder has the s flag set. I hope i can get a few pointers here how to get the seen flag working for all users again. On the old server the location variable for the shared folders had the variable INDEX defined which can not be used with sdbox. location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX Does that imply that sharing the seen flag can not be used with sdbox?

Does anyone have experience successfully setting up Dovecot OAUTH2 for authentication with Microsoft Azure? I'm not sure what to use as tokeninfo_url and introspection_url in the Dovecot configuration. I would appreciate any help and advice. -- Best regards, Max Kostikov

mail-crypt and mbox format
by cincodemayo_67＠yahoo.com 17 Feb '22

17 Feb '22

Hi, My Dovecot server of many years has been set up to use mbox email folders. I want to implement mail-crypt and after banging my head against a wall for a few days trying to get mail-crypt to work I decided to try it against a test instance of my server that I reset to use Maildir format and mail-crypt worked instantly. Does mail-crypt work with mbox format mail folders, or am I wasting my time unless I switch over to Maildir? The documentation at https://doc.dovecot.org/… [View More]
