SharePoint 2010 Install with the following symptoms:
1. full admin rights: I create an alert on a list.
2. I receive an email correctly stating the "FROM" (it matches the outgoing info on server). The email states that I have created an alert on the aforementioned list.
3. I never get an alert.
4. On some lists, I get an alert. Same site collection, different lists. Some lists never give an alert at all.
