I noticed that half the time when I send mail using the built in email client to osx lion, sometimes it hangs on the sending. I see the message in outbox and the little circle animation just turns and turns. the entire time I am typing this, I just checked back and it is still turning. I'm using iCloud with a me.com email address and standard account settings. ok, just checked and it finally went through. Is there some setting which optimizes which servers to use, or is there some special smtp server I should be using? Any insight?
