    Hi 

    If thats the case then you need to check your email routing part thoroughly

    Make sure that your domain is not in a open relay.

    Check your receive connectors configuration once again and make sure they are not in a open relay

    Configure reverse DNS for your SMTP connections

    Configure SPF record which will avoid spoofing your domain

    Also if you are using only Exchange 2013 antispam then i would suggest you to follow Best practices from Microsoft
