Adding `BAYES_HAM` to `symbols_disabled` should help avoid the issue (another approach could be rescoring `BAYES_SPAM` instead of disabling it). Likely related to #4787 and #4799

> @fatalbanana wdyt? The suggested changes look reasonable to me. I neither see issue with it; probably it should work as proposed I suppose.

We miss a way to specify that headers shouldn't be removed so far (see [here](https://rspamd.com/doc/modules/milter_headers.html#removing-headers) for documentation about `remove` setting); probably `remove = null` should do it (but that's so...

Are you not indeed quoting this setting somewhere in configuration (you should not)? What build of Rspamd? ~~~ $ docker run -u root -ti rspamd/rspamd:3.7.5 bash root@ab81ecea7cf8:/# rspamadm configdump greylist.expire...

> Please, try my example in first post. There is no expectation that that should work (rather the expectation is that something like `1d` (unquoted) reaches Lua as a number)....

What does `rspamadm configdump greylist.expire` show? Is `/etc/rspamd/modules.d/greylist.conf` integral?

It takes a moment for these servers to return a banner so it's necessary to set `timeout` to some larger than default value (maybe `timeout = 2` is good enough).

It worked for me; logs should provide some indication about a reason; redis cache key will need to be deleted for it to really try again.

Issue is in this alt text: ```alt=3D"bücher=E2=80=8C.de"``` It looks like a zero-width space indeed (but this is rather zero-width non-joiner).

The module is called `greylist` indeed. Probably the docs might better be referring to it as such...
