Today's fun #sysadmin tip: when migrating #mailcow to a new system it rsyncs every volume in its docker-compose file, so clean up any deleted mailboxes and shift #btrfs snapshots somewhere else or it will take considerably longer.

CVE-2023-34108: Manipulation interner Dovecot-Variablen in mailcow durch speziell gestaltete Passwörter https://dasnetzundich.de/cve-2023-34108-manipulation-interner-dovecot-variablen-in-mailcow-durch-speziell-gestaltete-passwoerter/ #CVE-2023-34108 #Security #dovecot #mailcow

waiting for ARM64 support in #Mailcow https://github.com/mailcow/mailcow-dockerized/issues/879

The server will get down tomorrow because I will do stuff and need to restart the server multiple times so yup get ready for some MAJOR outages — Because #mailcow takes A LOT to send, OVH support told me to do some steps to try and diagnose (incl. restart the server in rescue mode) so yup!

@itsfoss also you can use an tempoary emailadress in #mailcow

Da ich heute morgen Zeit hatte gleich noch Updates für meine #Mailcow sowie des Matrix Servers hinterhergeschoben... Das reicht dann für diese Woche. #updatetime :dasnetzundich:
