Bill,
Just as a note, one of the "new" things that spammers have figured out
is to use the account settings as defined in a computers email client;
yes, everytime I have seen this happen the user has gotten one kind of
malware or another on the system, normally things they have installed...
Most people (whether they should or not) save the password so that they
never have to type it in. Any way, once they have the account settings,
they just send that information to other computers they have, and start
sending things.
And yes, I have seen some accounts, normally webmail accounts, get brute
forced, but only when the passwords have been 4 characters or less, or
when a password has been set as varation of the username.
