01/04/2026: dovecot package on Arch Linux is on track to be fixed: libdeps and libprovides have been specified,
and icu dependency was removed to reflect the upstream removal of icu with Dovecot 2.4.2 released on Oct. 29, 2025.
postfix has been fixed since 10/11/2020.
libxml2 (required by php) has been fixed since 16/11/2025.
31/03/2026: Both postfix and dovecot are using the ICU library also known as International Components for Unicode.
When a new version of the icu package is released, dovecot needs to be rebuilt as reminded by checkrebuild:
if it hasn't, the operating system should not update the icu package.
29/04/2026: clamav-milter systemd unit and configuration was removed.
28/04/2026: opendkim and opendmarc milters were removed from postfix configuration and uninstalled.
rspamd milter is now installed and configured.
26/04/2026: clamav-milter configuration was removed from postfix.
The systemd unit was stopped and disabled because it was continuously becoming inactive.
Because of the Restart=Always directive in clamav-milter.service and the logrotate clamav process that stops the service.
Plan to migrate to rspamd.
07/04/2026: clamav-milter was removed from the SMTP server postfix's submissions service used by authenticated clients.
It still remains for the other services, in particular during the mail reception process.
15/05/2026: timer was rewritten again, now using wp-cli but had to update it first with wp cli update --nightly
wp cron event run --due-now is the best way for a monosite setup
14/05/2026: systemd timer was rewritten because it failed again.
I also clicked on the "Reset statistics" button going through WP > Newsletter > Help > Scheduler.
27/04/2026: logs for the related fail2ban jails are now daily-rotated with logrotate: no more CPU overhead.
21/04/2026: can no longer reproduce. To consider later for multisite setup: Calvalcade and The Perfect WP Cron
14/04/2026: issue submitted. Debugging mode enabled. fail2ban CPU overhead may have had an impact.

spamhaus-dqs is also required.
12/05/2026: SNDS filter result is YELLOW, which means 10% to 90% of time, a spam verdict is rendered on the newsletter
and this is irrespective of the user's safelist.
But it has an indirect impact on the engagement feedback loop.
The Exchange Online Protection safelist is the Validity Sender Certification but the user's safelist is equally important to move the needle.
In addition, Spam confidence level (SCL) is different per recipient for the same email
06/05/2026: plan to decrease Spam Confidence Level from 5 to 1.
Read doc about SCL
