Jim,

I would like to be able to send to my groups with a spoofed listowner
address. Groups.io doesn't recognize incoming mail from
[email protected]

From the New Topic page you can select the +owner address in the From field (if you're a group moderator). You can't do that from the Reply links, as far as I know.

I don't know if you can do that by email.

I suspect you would have to first go to the web site and join your group under the +owner email address, or allow posting by non-members. You might not be allowed to join with the +owner address, or you might tie something in knots if you do (best set that subscription to NoEmail if you succeed).
