Justin, I have had this problem before and still do from time to time. I have narrowed it down to something that may have nothing to do at all with Apple Mail, but here is how I live with the problem which I have thus far been unable to solve:
For several days, work colleagues were not getting my mail though I was sending it to them and nothing was ever bounced back. It turned out in my case that when I changed my ISP, the headache went away. I still have the same annoying problem with certain addresses whenever I use my mobile Internet broadband connection. Strangely enough, I can't send messages to other people who are using the same Internet mobile broadband ISP. I have never figured out the solution; I have just learned to live with it. If I need to make good and sure that someone is going to get the message, I use the ISP's webmail interface to send the note. Sorry I can't be of more help.
