Some may never try. Sendmail won't try in that case. But it is perfectly
valid to wait and try again. In such a case, the wait time is typical 3 to
5 days.
In the second case, it takes usually about 300ms to setup a tcp
connection, and fail. This 300ms isn't too long to wait. I doubt that
most people would notice. Quite a lot of fuss over 300ms, I think.
And I am just thrilled to see IE not go to MSN when I type in a wrong
name. I've been showing this to everyone. Most people like the
demonstration, and trust Verisign more than Microsoft.
