    Here is my MTA of global settings configuration

    Code:
    Protocol checks
    	Hostname in greeting violates RFC (reject_invalid_hostname) (YES)
    	Client must greet with a fully qualified hostname (reject_non_fqdn_hostname) (NO)
    	Sender address must be fully qualified (reject_non_fqdn_sender) (YES)
    DNS checks
    	Client's IP address (reject_unknown_client) (NO)
    	Hostname in greeting (reject_unknown_hostname) (NO)
    	Sender's domain (reject_unknown_sender_domain) (NO)
    Please note that the time is the spam mail exact time that I checked on the spam folder of my mail address.

    another favor please if you can advice me to the proper way (configuration) to reduce the spam messages

    Cheers,
