Hello, I face a problem on my shared hosting server. I have a user that regularly sends some newsletters to about 5000 recipients. When this happens, it prevents other user from sending and receiving message for more than 12 hours.
There are many options in postfix so I am not sure which one to tune up to prevent such an issue, can anyone advices me on that ? Any advices on my postfix (attached) configuration is also greatly appreciated... Thanks in advance. -- Lox [email protected]
