Hi all,
I would like to start disucssion how everyone of you is blocking SPAM and which configuration is the best to prevent spam mails.
I don´t use Greylisting because of delay for new Registration Mails etc....
Analyzing the Mails that are delivered to my Postbox after checking against lists like spamhaus.org an so on I saw this:
- Most of Mails having different "X-Original-To" and "To". Can I check if the "X-Original-To" is having a Domain that is hostet at my easyscp? What do you think?
- The IPs are changing often and it´s everytime a new one
- Often the "To" Header is Having GoogleMail like "To: <crimekiller627@googlemail.com>"
- SPF is often passed
Do you have more Ideas?
