Does main.cf need world readable?

f so, the setting in main.cf will be world readable also. Why does it happen? Since man.cf should be loaded to memory when Postfix start, it should not have file access. Best, Jacky -- View this message in context: http://www.nabble.com/Does-main.cf-need-world-readable--tp22406763p22406763.html S

How can setup a dedicated transport to slow down output-rate to yahoo in Postfix 2.3?

message at a time (perhaps a second). If the above is true, do I slow down the output-rate to yahoo?
