Resolution
NOTE: Large number of addresses in the SpamAssassin white/black lists may significantly reduce server performance.
- Connect to the server using SSH;
- Create a backup of Plesk databaseж;
-
Run the following SQL query to set maximum number of addresses. As an example, the maximum number of 150 mail addresses is given: you may choose appropriate number according to your needs.
For Plesk Onyx:
# plesk db "replace into ServiceNodeConfiguration values (1, 'mailServer', 'spamfilter_max_addr_list_length', 150);"
For Plesk Obsidian:
# plesk bin settings --set spamfilter_max_addr_list_length=150

It's not fixed in Plesk Obsidian, I've just tested the last version and has the same problem!
