Dear Experts,
Need your help in sorting out this issue:-
WE get lot of mails from different domains which are basically advertisements/promotions. The requirement is that these mails should get rejected at the server itself. We are using Postfix running on CentOS 4.6.
The configuration files are as follows:-
main.cf
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix
default_privs = nobody

Can we reject such mails coming from particular domains at the server itself so that these do not propagate into the network ?
