Just being able to change the email address on the community account isn't enough; I for one am subscribed to the lists with a different email address than the one associated with my community account (for spam management reasons). There needs to be a way to have multiple addresses or to specify which is to be used for the post.
This should also be fixed now. You can click Edit Profile, and add one or more extra email addresses there (after email verification of course), and then pick one of those to use for sending email.
