I was able to set it up, edit my new email and send it out to my test,
but finally I discovered that that it was sent out with from: WordPress <firstname.lastname@example.org> address
instead of the InboundNow settings of the Default Email Addresses.
Where can I change that?
I noticed the new WP Mail feature was still set to use the reply/from email address that the WordPress site uses. I currently have it updated to use the correct settings. It will be fixed in the next release.
Would you like me to link you to the latest development files? You could manually download them and install them if you’d like to jump ahead of the scheduled release.
