Comment 1 rgessner 2019-02-18 16:01:50 UTC
Easy workaround for me (based on information from https://danwalsh.livejournal.com/79643.html) is to change the owner of the /run/milter-greylist directory from 'grmilter' to 'root'.


But this should be fixed in the package itself.

> But this should be fixed in the package itself.

...to be more specific, /usr/lib/tmpfiles.d/milter-greylist.conf should be modified

from

d /run/milter-greylist 0710 grmilter mail

to

d /run/milter-greylist 0710 root mail

Hadn't noticed this as I added local policy for it as a workaround when the denials first happened and then forgot all about fixing it! Thanks for the report.
