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 database.
-
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 11.0 and earlier:# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e "replace into misc values('spamfilter_max_addr_list_length', 150);"
For Plesk 11.5 and higher:
# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e "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!
