If you are an alum with email forwarding setup, you should double check the forwarding. The recent MCoummunity upgrade broke a number of the forwards and you may need to set yours up again.
For those of you with no clue what I'm talking about: When you graduate from the U of M you lose your email account. However you can set it so all email sent to firstname.lastname@example.org is forwarded on to an email accunt of your choice.
Mods: I know this off topic, but it likely applies to a large number of people who use these boards. IT has sent out an internal note on this, but with email forwarding broken it wasn't like those people could be emailed.
If you send a test email to email@example.com and don't get the email at the destination account (the account you were forwarding emails to) you'll need to follow these steps. (http://www.itd.umich.edu/itcsdocs/s4384/). In some rare cases accounts were totally messed up and you have to email the helpdesk for help, because when they changed from LDAP to Active Directory they lost a bunch of info.
