I feel stupid for even asking this because it seems like something I'd normally be able to figure out but I've searched a bit with no results. Oddly enough, this only seems to have become an issue since the 10.6.4 update. In Mail, I can't seem to set the default email address to be used when composing a new email. At the moment, it's defaulting to the email address I rarely use, creating the need for me to change it manually for every email I send out. I did look in the preferences, but couldn't find it. Maybe I'm blind today, but could someone please help me figure this out? Thanks!
