Yesterday I tweeted that I was having issues with Mac Mail after installing Snow Leopard. Well, everything is functioning normally now.
What was the problem?
My wife figured out that my outgoing SMTP server changed for a few of my email accounts and the change was not reflected in my settings. She updated my accounts and voila, everything’s back to normal. Moreover, because I’m using MobileMe sync, these changes were immediately replicated to my other Mac. Beautiful, thanks honey!
