Loging in does not strip whitespace characters from the
end of the email address. If you login like this
username:"username "
password:"password"
you are able to log in. However, you are not able to
send any messages, trying to do so will produce an error:
An unexpected error occurred:
javax.mail.internet.AddressException: Illegal
whitespace in address in string ``godfoder @ufl.edu''
