BCC is the whole point of this bug. If a list requires 'explicit destination', the list address or an acceptable alias must be in the To: or Cc: headers of the message. The bug says acceptable aliases aren't checked and it means against the To: or Cc: headers. Checking against the envelope recipient is irrelevant since if the list weren't the envelope recipient of the message, the list's chain wouldn't be seeing the message in the first place. -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1170726 Title: The LMTP server needs to check acceptable aliases To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1170726/+subscriptions
