Does just what it promises Rated 5 out of 5 stars

This is a great extension for people like me who dump all their incoming mail into one account but still want to reply from the correct address. When you reply to a mail Correct Identity will automatically select your identity the mail was addressed to. The options also provide you with a way to set the default identity for each account or override selected identity depending on sender addresses - but that is almost unnecessary. This extension will do its job reliably and without ever bothering you with configuration. Very recommendable.

This review is for a previous version of the add-on (1.3.1).
