I am running IBM Lotus Domino Email Server with Symantec Premium Antispam.
From past few days, I am receiving SPAM emails that pretend to coming from my own email address. example my email is JOHN@MYCOMPANY.COM , and in my inbox, i see spam email coming from JOHN@MYCOMPANY.COM. (and in header different ips or domains showed, subject is different everytime , see below code)
how can I prevent such spam emails. as sometimes they contains harmful .docm or sometimes it shows advertisements.
Following is full header.
