One of the receiver shouldn't have got it. Actual results: The receiver read it because he was in CC but I didn't notice it. Expected results: An alert should have warned me, like Thunderbird does it when we forgot to add a joined file in a mail talking about joined file. I'm suggesting that Thunderbird has a list of sensitive mail that the user can fill. When a mail is sent with one of these adresses in one of the "to", "cc", "bcc" field, a warning displays when sending the mail.
If what you want is to block addresses based on the identity you are sending from, then there are addons that will do this, like https://addons.mozilla.org/en-us/thunderbird/addon/flexible-identity/ Or you want a list of email addresses that shouldn't get email?
Do you know the alert system when we talk about a joined file in the mail content but don't join a file? I want the same thing when one or some peculiar mail adresse(s) are in one of the "to", "cc", "bcc" fields.
I believe this functionality is already available via the use of an add-on. The Correct Identity add-on is capable of associating given accounts with given addressees and raising a warning when appropriate. The SUMO support site would be a better place to continue this discussion. https://support.mozilla.org/t5/Thunderbird/bd-p/Learn-Basics
