^ good point, it should ask for user password first, so this basically comes up after login.
but i'm fairly sure it's the standard password managing / keyring app that gnome has been using for a decade.

that's because it's some password managing app asking for it, and not the email app itself.
have you used that email app before? created an "Email" account? if yes, i'd say it's safe to enter that password and put a check for keyring.
you still have to enter your user password, right?
