Rated 5 out of 5 stars

OK, I modified the "your group domain name" table, I filled it with only the domain part of my own email addresses.
Now I see, that the "TO:" addresses of e-mail appear either in the "Your domain address" either in the "Other domain address".
But I don't see the "From:" address, so how can I verify and confirm here, that I use the proper "From:" address?

This review is for a previous version of the add-on (1.3.5). 

Confirm-Address doesn't check "From:" address, because any mail user agent never sends mail to "From:" address. Your question is received as a new feature request.

When the add-on stops to confirm the addresses, the Other domain address is filled with the To: address of the e-mail, however the Your domain address isn't filled.
I tried to add my from addresses to Options/ Your group domain name, but no success, Your domain address is till not filled
I don't know how to further.
If I confirm the To address, TB will send the email successfully.
Please help!

Don't you set your "full address" into options > your group domain name? You need to input only domain name (after @ mark). Please retry.
