Tried upgrading Ubuntu on my mail server. Broke MailScanner config. Had to scramble to figure out how to reconfig postfix to deliver mail directly, instead of holding it for MailScanner to pick up. I really need to find a way to migrate away from doing my own email admin.
I finally just gave in and pointed my personal domain at Google Apps. I don’t have to fuss with it any more. I used a perl script to migrate all my email out my old IMAP server and it has worked well for me.
