I'm running dovecot 2.2.27 in a alpine based docker container and want
to log to /dev/stdout. I therefore added this setting:
log_path = /dev/stdout
Logging works fine so far.
Now I've added a quota-warning script. With the log_path setting above
the script creates warnings like:
Oct 28 10:27:01 quota-warning: Error: Can't open log file /dev/stdout:
No such device or address
Oct 28 10:27:01 quota-warning: Fatal: master: service(quota-warning):
child 460 returned error 75
When I change log_path to something like /tmp/dovecot.log everything
works fine.
Dovecot itself is started via s6 with a run script like this:
#!/bin/sh
exec /usr/sbin/dovecot -F -c /etc/dovecot/dovecot.conf
What could cause this issue and how could I fix it?
For the record here's my doveconf -n output:
# 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf

Try adding
service quota-warning {
chroot }
It won't chroot it then, but I'm not sure if that has a huge security
impact.

Thanks, I've tried it. Unfortunately it didn't help. The error message stays the same.
