  • That email (which is what Groups.io sent out as the from address) should be forwarded to <bbbbbb--at--btinternet.com>.
  • --eq-- is a valid character in a group name, so how does groups.io decide whether to forward outwards or submit into a group?
GIO doesn't do any forwarding.  A Reply to Sender should go directly from the person replying to the original poster same as any other email they'd send, not via GIO.  When this error occurs, it's because the email client/service isn't properly observing the headers for From:, Reply-To:, etc.  The only solution I'm aware of is for the person to 'unmunge' the address properly before sending.  That would be bbbbbb--at--btinternet.com in this case.
