06 July 2021
- 89: fetchmail feature: skip fetching read mail.
New `imap_search` and `imap_on_delete` to fetch only `Unseen` messages and set them to `\Seen`.
- add `-s/--searchset` to override imap search and setting of flags for all rcfile's in the command
- if no `--rcfile` and no default `getmailrc`, then use all files from the `--getmaildir` folder
- fix "SyntaxError: Non-ASCII in file, but no encoding declared" (only Python 2.7)

- 79: UnicodeEncodeError: 'ascii' codec can't encode character in position
- 78: Don't encode pure ASCII X-getmail-retrieved-from-mailbox
