Louise,
Then I think I understood they might actually still be receiving
email at a different linked address so I stopped removing bouncing
members. Not sure if that is a correct assumption.
I think to receive email at a different address that other address would have to be in your manage members list. So in that sense it would be safe to remove the bouncing address.
On the other hand, the behavior of Yahoo Groups with respect to on-line (web) viewing of group content when your email address is in bouncing status has varied over the years. Or, at least the descriptions and stories have. I think I've heard it said at various times that a) you can't access the group's pages while your subscribed address has bouncing status; b) you get a warning banner if you access the group's pages while your subscribed address is bouncing; and c) you are blissfully unaware that your subscribed address is bouncing.
I think I've experienced (b) in the distant past, but the memory is a bit fuzzy; might have been (a).
Some of these differences may be accounted for by incomplete observation or description of the circumstances. For example, a user with two or more subscribed email addresses may not be paying attention to which is in effect while browsing the group's pages. But some of them may relate to actual changes in Yahoo's behavior.
It is a little difficult to determine the truth by experiment, as you need to be able to create a subscription with a test address that is valid (you must verify it at some point while subscribitng), and then cause the address to go into bouncing status.
To make matters more confusing, my understanding is that the current status of Yahoo Groups' bouncing mechanism is: defunct - it reportedly has ceased putting addresses in bouncing status even when the address is in fact rejecting messages.
"This message cannot be viewed because it was sent from another
group" can be explained. I think it just refers to the last email
sent by the yahoo member ...
Close. Actually your group member was sent an email message from another group, which bounced (was rejected by the member's email service).
