Just before I go ahead and do so, is it safe for me to just add mailbox_size_limit and message_size_limit directives to the bottom of the /etc/postfix/main.cf file? I've noticed that they don't already exist, so what are the defaults? I can see message size is 10MB (ehlo localhost) but can't see the default for mailbox size. Do these settings have to be system wide? indie
