Block SMTP Relays with Fail2Ban
If your Postfix mail server is constantly bombarded with spammers trying to relay through your system, you might be getting tired of huge log files and incessant spam connects.
To help reduce this we’re going to create our own filter for relay rejects.
Note: There are no refunds once the transaction has been completed. If you have any questions, you should ask them prior to completing your purchase.
