No, this isn't DMARC; Google Groups only mangles the From field when it needs to do so for DMARC purposes.
The problem lies with the regrettable (but very common) practice of lists munging the Reply-To field so that the list address is listed, thus directing replies back to the list. Mail.app for some reason removed explicit support for replying to the Sender, so you will have to burrow in the headers, find the From line, copy the address from the menu (click the author's name), and manually send mail to the recipient. Sorry about that. Because so many lists do this by default, I now hit Reply-All instinctively, because Reply alone is almost always completely useless. Simply get into the habit of checking the composer window before you hit send. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
