It’s DMARC. What you’re seeing there is Google Groups (and other mailing list managers) rewriting the From: header so it is the list address, so that recipients of the mailing list traffic which check DMARC policy for the From: address don’t subsequently bounce the message and get themselves unsubscribed from the mailing list. It just so happens that iCloud has a DMARC policy of quarantine which means put it in the spam box, and Google Groups compensates accordingly; other mailing list managers only react to a reject policy (hard fail). DMARC is an utter disgrace but it’s here to stay, so you’d best get used to this state of affairs.
To find the legitimate sender address on Google Groups: it’s in the “X-original-from:” header, so open a message, go to View, then Message, then Raw Source. Enter the raw message itself, then VO-F and enter “x-original-from” and you should find the original sender name and email, which you can then copy. On Mailman 2.1.16 or better, you can “reply all”, then extract the name and address from the CC field, as Mailman helpfully drops the sender’s address in there if the list is configured for replies to go to the list (otherwise it’s in Reply-To: and hitting “Reply” just works as usual). This I think is the least worst option that doesn’t involve intermediate forwarding addresses, which is the path LISTSERV(R) chose to go down, though almost nobody uses that software nowadays. You can thank the spammers. Also thank the militants who provided a cure worse than the disease. They have a cure for the cure, too, called “Authenticated Relay Chain” which will, if implemented, simply further entrench the dominance of a few key players, by allowing known mailing list distributors to sign off the mail without impacting the original From: header.
