Hello, I apologize if this is in the wrong section, it seemed most applicable and the best spot to get an answer. One username for a domain I own is getting tons of spam e-mail where they are spoofing the same e-mail address to get through the spam software. For example, if my e-mail is: that address is showing as the to: and the from: so I can't block it. The IP it belongs to varies each time as well so blocking that isn't helpful. The issue is not happening with any other usenames on the same domain. Any idea how I can defeat the spam? Thanks in advance!
but in some cases, if the mal server of the recipient does not check for SPF, then it defeats the purpose..
check for headers regularly and check if the mail domain resolves to he given IP.. if not.. it's spoofed.
USe spam assassin with mail scanner it will help you in this black listing and spoofing, what control panel you use and what mail server?
you cant do anything about spoofing you can make a simple php script with the email you like to "spoof" it.
yes you can but a spam filter will flag it as spam most of times because it is spoofed. Using SPF will increase the odds of it being flagged as spam, if the sender domain also uses SPF. And if he spoofs your domain....well you control the SPF records. They would have no way around it.
