One of my group members has had problems with a ¡°send mail as¡± address. He gave me the information below. I don¡¯t totally understand it but thought someone here might.

In plain English, this kicks in if one uses gmail to handle other accounts, using the
Send mail as:
(Use Gmail to send from your other email addresses)
...feature in the gmail settings.
What happens is that gmail puts the "send mail as" address for the desired account in the 'from' field of the sent message.
but it also adds a 'sender' field in the message headers, with the base account address in it (the actual gmail user login address), which is not the same as the 'from' address.
Apparently the groups.io software looks at the 'sender' field, if there is one, and uses that to determine list membership. Since in this case it doesn't match a subscribed address (which is in the 'from' field), the message is rejected.
