Attention:

(1) In a postfix configuration file, parameter rows and comment lines cannot be in the same row;

(2) The value of any one parameter does not need to be quoted, otherwise, quotation marks will be used as part of the parameter value;

(3) The implementation of Postfix reload after each modification of the parameter and its value will be effected, but if the inet_interfaces is modified, the postfix should be restarted;

(4) If a parameter has more than one value, you can place them in a different row, simply by placing one more space in front of each subsequent row; Postfix the first character as a space or tab text line as the continuation of the previous line;
