Folks
I am the postmaster for @compuserve.com and @csi.com (the "i" is
important, @cs.com is someone else).
A couple months ago my email traffic doubled (from 1 million a day to 2
million a day). After some investigation I found that a spammer was
sending from [EMAIL PROTECTED] and I was getting the back splatter. I
cancelled the [EMAIL PROTECTED] account and thought the spammer would soon
stop. Turns out I was wrong, the spammer is still at it.
Sure, since they are forging the address anyway...
I just received
several hundred attempts to return email from @walmart.com.
To make a long story short, please feel free to block [EMAIL PROTECTED] You
can verify that the address is invalid first if you wish.
Is there a better way to handle something like this?
SPF or domainkeys. Then Walmart would know that the message being sent
was forged.
That is a reasonable suggestion but my customers don't always send email
from my SMTP servers. As I understand SPF I would have to list my
servers and says "It is not an error if it comes from some other server."
Would that not be a problem for Domain Keys also?
