I am curious if anyone is familiar with HELO email. In the headers of the mail I have been receiving, it shows up in the line Received: here are some examples: Received: from unknown (HELO email) (pipirka20sm@60.21.161.73 with plain) , why would the numbers change if the mail is always coming from the same computer. Here are some of the other different #'s: (pipirka20sm@98.197.203.161), (pipirka20sm@80.73.48.232), (pipirka20sm@60.30.240.252), and so on. I think no more than 2 or 3 letters at a time use the same HELO location. Also there is no line where the X-Mailer line should be. So I have no idea if this is a form of The Bat! Does anyone know what this could mean?

HELO and EHLO are SMTP protocols. Try reading

for more of an explaination. Often you'll see HELO (unknown) in an email, and it's usually then followed by a spoofed IP Address. I'll move this out of scammers now as it's not really about any single scammer.

I appreciate the link and also thanks for moving this post to this forum, I didn't mean for it to end up in the scammers
