Task #2257
Updated by Guilhem Moulin almost 5 years ago
This issue is about refactoring the main mail server. Possible improvements include: Base system: * Upgrade to Debian 10 Dovecot (IMAP): * Change mail storage format from maildir to mdbox, possibly compressed Postfix (SMTP): * Replace amavis by rspamd amavis * consider setting Postfix' @notify_classes@ to empty * -switch switch to Milter- Milter * Guilhem proposed to use systemd <pre> Assuming you're using systemd as PID 1, a quick and dirty fix would be to tell it to auto restart the service. Rather than editing the unit file shipped by the package (which would be overridden by the next amavis update), I'd go for an override systemd.unit(5) file instead: $ mkdir /etc/systemd/system/amavis.service.d $ tee /etc/systemd/system/amavis.service.d/override.conf <<- EOF [Service] RestartSec=1min Restart=always #Restart=on-abnormal might be more appropriate, see #systemd.service(5) for details EOF $ systemctl daemon-reload $ systemctl restart amavis You can see if the override systemd.unit(5) file is taken into account with `sudo systemctl show amavis.service | grep ^Restart`. </pre> hostmaster alias * consider switching to local mailbox only in case of too many notifications domains * switch to DNSSEC and TLSA records if feasible
