Gmail側で「他のメール アドレスを追加」をしないといけないのが面倒だが、それ以外は楽になります。

This review is for a previous version of the add-on (1.0.2).

Does not work. Assumes that aliases will have + signs in them or something.
If you want to be fancy, just add a regex field.
But that's not even necessary.
Just compare the domain the email was received at with my identity's domain, if it's the same, use the recipient's address.

Thanks for the feedback — at the time you reviewed, you were right: the extension only handled plus-addressing (user+alias@domain.com), so aliases on your own domain simply didn't match.

That's since been fixed. Newer versions add two more alias methods you can pick per account in the settings:

- Own domain — alias@yourdomain.com
- Catchall — anything@yourdomain.com

Both do exactly what you described: they compare the domain the mail was delivered to against your identity's domain, and if it matches, reply from the recipient's address — no + required. It also reads the delivery headers (X-Original-To / Delivered-To), so it still finds the right alias even when it wasn't in the To/CC line.

One thing to note: the feature is opt-in per account and defaults to plus-addressing, so you'll need to open the extension's settings once and select "Own domain" or "Catchall" for your account.

If you get a chance to try it again, I'd be glad to hear whether it works for your setup now.
