I am using zimbra server as our email server. Today I saw some weird emails in my inbox. The From and To address both belongs to my email address. The header of the email.
To: firstname.lastname@example.org From: "email@example.com
But Received address is the following.
Received: from p3smtphosting04-02.prod.phx3.secureserver.net (p3smtphosting04-02.prod.phx3.secureserver.net [188.8.131.52])
Is there any solution if To and From address is my own that should go to SPAM folder. I know From address could be anything and generally this could not be stopped but at-least it goes to Junk. If there is any general rule I can add to spamassasin, so if the From and To matches it should be considered as SPAM.
