I am trying to blacklist 2 domains I  get spam from,
@126.com
@163.com
I am adding them at the ireadadmin page :
iredadmin/profile/domain/general/<DOMAIN>#profile_wblist where it states Mails sent from blacklisted senders will be quarantined by default.
but I am still receiving them, why might this be ?

I added the relevant plugin listed below

This feature requires iRedAPD plugin 'amavisd_wblist', please make sure it's enabled in file /opt/iredapd/settings.py.
