Spam whitelist limited to 100 addresses in Plesk Control Panel
By default Plesk only allows you to have 100 email addresses listed in your whitelist and blacklists.
It was done to limit CPU usage by spamassassin, because by adding several hundreds of mail addresses into one of the lists user can decrease server performance. Or user can advisedly, add a lot of addresses into list, send a lot of mails and all server will be very slow.
In Plesk CP user can see how many addresses he can add into list(100 minus already added quantity of addresses). If before upgrade to 8.1 (this limit doesn’t exists in earlier version) there were added more than 100 addresses user will see negative number.
