Rejecting continuously changing incoming mail in postfix

Hey everybody,

I've read many post close to my subject regarding blacklisting incoming emails, but non of them described what I really want:

How can I reject a continuously changing email from my postfix, here is what I mean:

I think you got what I mean, the thing I've taken from the posts I've read is that I created a sender_access file hashed it and added the:
smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/sender_access
to postfix configuration

The sender access file reads:
abduooo* REJECT

But that didn't work, I know that there is some magical slashes and dots to be added to the sender_access, but I don't know which.

Can anyone please help me?
Thanks in advance

Unless you expect to receive mail from some legitimate, try simplifying your blacklist to *@googlegroupscom.

Here is an article on Configuring Postifx. Scroll down to "Fighting against SPAM" for an example of what to add to your config. Use for further searches on configuring postfix to fight spam.

You may have better luck if you combine postfix with spamassassin. Spamassassin has rulesets to filter spam on a variety of subjects. They are text files which you can edit to your needs, or create your own. You can get them here:
