I have had an Ubuntu Server (12.04.2) running for quite some time. It runs a variety of Server apps, including hosting my personal website. I was playing around with WooCommerce on WordPress the other day, and wanted to figure out how to get the email notifications to work. In my endeavors, I installed (and uninstalled; well,
apt-get purge'ed) both sendmail and postfix.
After I was done playing, and uninstalling everything I had installed (since I could not get either to work), I noticed that a prompt telling me that I had mail would pop-up every time I logged onto the system. First I thought, oh, I just need to mark 2000 mails as read. I did that (thankfully there are ways to do this without going through 8+ months of mail that I didn't even know I had). But now the prompt loves to tell me that I have 'No mail.'
How can I get rid of this Prompt? It drives me crazy. I went many, many months without it, and I don't need it or the mail that it wants to tell me I have. Even Better, Can I turn off the local mail system entirely?
Thanks for your help. :0)
