Not sure if this is a bug or feature request, but currently when using rspamd, the greylisting setting of the users' spamfilter policy is not respected, if the "Enable greylisting" checkbox is disabled, then greylisting within rspamd is explicitly disabled as well; if "Enable greylisting" is enabled, things are setup correctly in rspamd settings, but also postgrey is set to always greylist, which is not what I want. I want to use rpsamd's greylisting at the policy specified threshold, and not greylist everything via postgrey.
I can see a use case/expectations case for the current behavior as well, ie. "Enable greylisting" is not checked, you might expect it to be disabled in rspamd even if the selected policy specifies it should be used.
Change the wording of "Enable greylisting" to something more like "Always greylist" ("Force enable greylisting" ?), and have the checkbox only control the use of postgrey (so rspamd's policy settings (greylist level) are always used).
Add a server config setting to allow the admin to choose whether the "Enable greylisting" button should override the spamfilter policy or not.
