I am on a local city commission. As part of this, they gave me an email address (made me unhappy, but whatever). They sent me an email to my personal email address telling me how to log in to my city email address, explaining that my password was a trivial algorithm based on my name, followed by a number an exclamation point. This was a form email: every single address in the entire city has the same password format (with the same number, to be explicitly clear). They disabled the feature to let people change their password. So... anyone can log in to the email account of any official in this city and do stuff like delete mail before they see it (as even if they have audit trails turned on for administrators, the official can still delete mail from their own perspective, and would never know if someone helpfully deleted it "for them").
