For the last 2-3 days, my mail.app program has had that tiny caution icon informing me that my mail cannot be synced. I can log into me.com just fine, and my other two email accounts, both gmail accounts, work just fine. In an attempt to figure out what's going wrong, I have disabled Little Snitch, even completely uninstalled it. I have also set my firewall to allow all incoming connections. Other than those two exceptions, I have no other applications on my mac that would interfere with network connections. Has anyone experienced this before? I have restarted; done everything that I can think off. In addition to this issue, my Adium IM is messing up as well: can connect and use any service except MSN. This only started this morning, a day or so after my mail.app began to get screwy. Currently verifying and repairing permissions. EDIT: well d*mn, now Adium won't connect to AIM either. Haven't reinstalled Adium yet, but I have a sneaking suspicion this has to do with something other than just Adium, since mail.app is screwing up as well.
