How to increase the maximum number of addresses that can be added to the SpamAssassin White or Black list

  • Parallels Plesk 12.0 for Linux
  • Parallels Plesk 11.0 for Linux
  • Parallels Plesk 11.5 for Linux


I cannot add more then 100 email addresses to the SpamAssassin White/Black list through the Parallels Plesk Panel (Plesk) Control Panel. After 100 addresses are added, I receive the following notification:

Error: Only %available% unique email addresses can be added.


Warning: Only 100 first unique e-mail addresses will be added.


Plesk has a default limit on the number of email addresses that can be added into SpamAssassin black/white lists. This is because a large number of addresses in the SpamAssassin white/black list may significantly reduce server performance.


  1. For Plesk 11.0 and earlier, use the following SQL query to set the maximum number of addresses to 150:

    # mysql -uadmin -p`cat /etc/psa/.psa.shadow ` psa -e "replace into misc values('spamfilter_max_addr_list_length', 150);"
  2. Since Plesk 11.5, some configuration settings were moved from the misc table. To increase the limit on the number of email addresses in SpamAssassin white/black lists, use the following SQL query:

    # mysql -uadmin -p`cat /etc/psa/.psa.shadow ` psa -e "replace into ServiceNodeConfiguration values (1, 'mailServer', 'spamfilter_max_addr_list_length', 150);"
