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:
abduooo+bncCIr7stnbBBCssufsBBoEzTHSKg@googlegroups.com
abduooo+bncCMfZgc-iExCKr-fsBBoEMzorbA@googlegroups.com
abduooo+bncCLf5kv6MHRCtmefsBBoEjYnAAQ@googlegroups.com
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 main.cf configuration
The sender access file reads:
abduooo*@googlegroups.com 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
