I would like that when setting up the default mailbox that the default SMTP server change would be asked as well.
I have sent by mistake an email using e-mail address I absolutely not want to be assosiated with and would like to be able to keep reading the mail using the same client.
In my opinion asking default mailbox for incoming and outgoing mail wuould definitely keep users up-to-date on default e-mail address used while sending e-mails.
