Would be great if you could add per-user email encryption into iredmail package. I tried to configure Dovecot mail-crypt plugin with per user encryption (keys generated based on a user's password) using this tutorial: https://workaround.org/ispmail/buster/o … ent-125882 but it involves changes to mysql databases. I wasn't able to locate the db containing virtual users of iredmail. Perhaps you could add this functionality to the next release? Merry xmas!
