Any clue why it won't work under Plesk?

[rallisf1]

I am using latest Plesk Obsidian 18.0.37 and running rspamd 2.7 on a different server.

I got milter filtering running fine and global-spam.sieve works as well but learn spam/ham does not.

• sieve_pipe_bin_dir path is correct
• learn-spam.rspamd.script has proper permissions
• I have assigned my rspamd url to RSPAMD_CONTROLLER_HOST
• I have created the password file with only the password inside

Unfortunately Plesk does its own logging (none for this case), thus I can't debug to see what's happening. Changing mail_debug setting has no effect :(

P.S. I know Plesk is a custom solution with its own support but they couldn't help me.
