We are sorry to report that we have a bug in dovecot, which merits a CVE. See details below. If you haven't configured any auth_policy_* settings you are ok. This is fixed with https://git.dovecot.net/dovecot/core/commit/c3d3faa4f72a676e183f34be960cff13a5a725ae and https://git.dovecot.net/dovecot/core/commit/99abb1302ae693ccdfe0d57351fd42c67a8612fc Important vulnerability in Dovecot

Hello, I sent this into the Linux Kernel Btrfs mailing list and I got reply: "RAID-1 would be preferable" (https://lore.kernel.org/linux-btrfs/7b364356-7041-7d18-bd77-f60e0e2e2112 at lechevalier.se/T/). May I ask you for the comments as from people around the Dovecot? We are using btrfs RAID-10 (/data, 4.7TB) on a physical Supermicro server with Intel(R) Xeon(R) CPU E5-2620 v4 @
