Comment 1 for bug 855150

Aside from the other problems, Launchpad also seems to be sending mail

1- to users whose account is inactive <https://launchpad.net/~ian-clatworthy>
2- to email addresses that are obsolete, for accounts that are still active <https://launchpad.net/~henninge>

This could possibly be split to a separate bug.

Perhaps there could be some systematic guard against those things happening for all Launchpad mail sources. Obviously it is unacceptable to send mail to people who have shut down their account.
