Thanks Julie.
I wish I had read your message 45 minutes ago!
I did figure it out though!! I just kept playing with those options and wound up checking the "Require SSL connection" as well as "Outgoing mail requires authentication" options. Now I don't get that annoying message: "Messages can't be downloaded..." After sending myself a test message, everything seems to work great!
Thank you for taking the time to reply. Perhaps this will help another newbie later on!
