    Default blocking a domain partially

    Hi all,

    we are struggling with an issue.. the issues is as follows..

    sender domain and receiver domain are same.. so
    the sender should not send any kind of mail to same sender domain..
    the sender can send mails to other domains.
    The send can receive mails from any domain even from senders domain..


    so in short a sender should not send any mail to its own domain but should receive mails from it.
    Thanks,
    Surendra Kumar Anne

    Default

    It is called spoofing and used to send spam. Try all of the following with your MTA


    • Reject all email if they do not have a valid hostname or proper email address.
    • Setup spamassassin
    • Set SPF to avoid from: and to: domain based spam.
    • Configure blacklist & whitelist
    • Configure RBL
