Rated 3 out of 5 stars

Still add 2 signs:
- correct one (the one I configure for a sender) : but before the replied email body
- wrong one: (the default account sign) after the replied body

Nice addon.

Exactly what I want: When writing the new emails it works correctly. , But ....

When answering an email from one of the senders included in the list to detect, the extension adds both the signature by default (below the text to be answered, as configured in the default identity) and the signature corresponding to the rule of detection (on top of the text that is answered, even if the identity to be detected is configured to be set below the text to be answered)
