Although I have not seen this issue on my group, I do have a btinternet.com address, so I tried sending a test message to the owner and I believe it was sent out to the group.? I have two memberships of the group, one has owner status and the other does not.? Unfortunately the one that does not also is set to "no emails" (so I don't get everything twice!) but if I log on under that name I see the message.
Since Chris in his latest message has not copied the letter he was responding to, I am not sure what the "Guess" is that he refers to.

I am moderator of a group. I have seen messages sent by members to the "groupname+owner" address which end up going to the "groupname" address and are thus sent to all members. This looks like a bug in parts of the internet itself. Most of the time its OK but for some members (including me) it happens every time. It looks like the bug is that an internet on-route server is interpreting the + sign as the end of the "user" part of the email address.
Have any other groups seen this effect? I think it may be very difficult to track down where this bug is occurring, and I would like groups.io to consider the possibility of a work-around at groups.io which will not be vulnerable to this bug. Perhaps changing "groupname+owner" to "owner.groupname" or something similar which doesn't use a character (like +) which could be treated as the end of the token.
