Blacklist are not working in Plesk

[Thomas Becker]

Hello,
the blacklist for domains seems to not work correct (blacklist in each mailaccount). There are added some entries like *@xyz.com but there are still coming mails through from domain xyz.com. The blacklist in general seems to work because other entries in blacklist are working.

Could the reason be that in "Received:" there is no @ symbol and only "from m15-111.xyz.com"?
