Can't receive email on mailserver, email too large, how to fix this?

shm I think it should be too big for your email attachment. Add this parameter to your postfix configuration file and restart. It means to set your email attachment size limit to 50M message_size_limit = 51200000

after saving, this parameter does not change and is restored to the old value. Where else is it possible to make a change?

Starinenko Is it possible to modify the file directly? Restart postfix service after modification /etc/postfix/main.cf

Can't Receive email, error: 552 5.3.4 Message size exceeds fixed limit

does not help, I make a replacement in the file, I overload it, the parameters return to the previous ones
