I ran into problems with creating user accounts with my WordPress install.
WordPress uses Postfix to send email to my ISP which is Comcast.The problem is it sends it as sender www-data@localhost. I have to google for the right solution for this. The Postfix package in Debian doesn’t have enough Documentation so I have to the online Documentation.
Manpages is only helpful if you know what you are looking for. So ,thanks to google I was able to get this http://www.postfix.org/ADDRESS_REWRITING_README.html#generic
Basically,what it does is rewrite the sender address to my regular comcast address.Cool!
