new email settings sort of work in iMac Mail

I got the "update your settings" email and dutifully made the changes in the Preferences of Mail. Incoming test message worked fine. Outgoing test message hung for a while, then demanded my password (which it should already have had, but I'm guessing timing issues made it forget that), and eventually passed the message. I REALLY hope this behavior was an aberration because taking four minutes to send one small plain text message seems ridiculous.

It would be lovely if Verizon instructions covered non Windows boxes, but fortunately I've played with my Preferences before so it wasn't a totally foreign thing.
