From 4977d7c1d80ac0caf94914fbf9be8471d056c906 Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Sun, 8 Sep 2024 02:10:41 +0200 Subject: IMAP: Adjust dovecot configuration to bullseye. Provisioning /etc/dovecot/conf.d/*.conf is a pain on upgrade so we consolidate that by reverting these files to the distro-provided ones and shipping a single /etc/dovecot/conf.d/99-local.conf override instead. --- roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf | 427 ----------------------- 1 file changed, 427 deletions(-) delete mode 100644 roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf (limited to 'roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf') diff --git a/roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf b/roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf deleted file mode 100644 index d74b026..0000000 --- a/roles/IMAP/files/etc/dovecot/conf.d/10-mail.conf +++ /dev/null @@ -1,427 +0,0 @@ -## -## Mailbox locations and namespaces -## - -# Location for users' mailboxes.
