Why don't I receive my own postings to a list?

The message will be in your Sent Mail folder/label, but not your Inbox. Google de-duplicates messages. The following are ways to confirm that your email was posted:

  1. Ask another group member.
  2. Add another account you can access (personal email or functional account) to the group.
  3. Look in the archive of messages on the home page of the group (if archiving is enabled).
