Comment 154 for bug 1215882

This problem has really been throwing me for a loop. CenturyLink for some reason is frequently issuing 421 errors. Because of the way Tbird was acting, I thought it was just a warning and since it copied the message to the "sent" folder, I had a record of sending the message, though it never went anywhere. Really awful to tell people you had replied to them and yet you actually had not.
