badmailfrom

I need to block an email address in Qmailtoaster.(Incomming)

Take a backup of file /var/qmail/control/badmailfrom
If we add

shivinvijai@gmail.com
yahoo.com

Save
(No need to reload cdb)

Qmailserver will block any mail from shivinvijai@gmail.com and it will block any users from domain yahoo.com (user1@yahoo.com,user2@yahoo.com) etc...
