Unfortunately it doesn't seem to work on the current version of Thunderbird (24.5) - email gets sent without displaying any alert.

This is a simple plugin that does the job well. Never had any problems with it at all..

Only improvements I could think of would be:
- add a list of the "bad" email addresses to the alert in some easy to read format. Confirm-addresses 1.2.3 is for me a worse plugin, but has a slightly more "pretty" interface.
- cope better with subdomains - when sending from me@foo.com emails in both foo.com and bar.foo.com are both valid (for me at least), so having an option to allow this would be good - or perhaps just have two separate warnings (one for totally mismatched domains, one for those that just don't match the entire string after @). Currently the entire subdomain/domain has to match.

This review is for a previous version of the add-on (0.6).

Quite important tool, but where can the domain name be edited or additional domain names be added. Required if multiple domain names are used inside a company.

I can turn on "Address Autocompletion" option without worrying about sending confidential e-mail to external parties :)
