If an email is sent with the addresses of two or more mailing lists in the `To` headers, then Ponymail will store identical copies of that email in `mbox_source` except that the `List-ID` headers will be different. This has been tested with Mailman as the mailing list software. Since the discussion topic is the case where `List-ID` is for some reason not added, and since the rest of the `mbox_source` values are identical apart from that header, the values would be exact duplicates if `List-ID` were not added. As for examples, any email with two or more mailing lists in the `To` header should suffice. The test did not involve any special conditions or setup, just writing a regular mailing list message in a regular email client. Nor was there any Mailman or Ponymail configuration that would affect the test. This is not the only possible example scenario, as mentioned. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
