I know this may seem simple and stupid to most of you but I was looking through my configuration and was curious what the parameter 'setgid_group = postdrop' in my main.cf actually means. Yes I've read:
setgid_group (postdrop): The group ownership of set-gid Postfix commands of group-writable Postfix directories. I am just not really sure I understand what that means or how to apply this in theory. I am just using ISP style configuration with one domain setup for Postfix and it's the final destination for mail so would this still be needed in my configuration? Can someone help this lost soul out? -Carlos
