Correct Identity

Correct Identity helps you to use the right identity when sending messages by:

letting you better configure default identities to be used when composing new messages from scratch.
detecting and using the identity for which you received the message you're replying.
you can improve this detection by specifying aliases (alternate addresses, sender names, domains, etc., regular expressions supported), or instead opt-out identities for detection.
changing identities on the fly when typing recipients that match aliases.
warn you before sending a message from an identity if its recipients match one or more search terms you configured for the identity (regular expressions supported).

Source, changelog, issues and feature requests are maintained at GitHub.
I have very limited time for maintaining the addon, so additional contributors and pull requests are very welcome!

Fixed v57+ compatibility, with thanks to Martin Zillmer

Some add-ons ask for permission to perform certain functions (example: a tab management add-on will ask permission to access your browser’s tab system).

Since you’re in control of your Thunderbird, the choice to grant or deny these requests is yours. Accepting permissions does not inherently compromise your browser’s performance or security, but in some rare cases risk may be involved.
