You need to quote the name:

  - name: "067"
    url: https://067.cz/rss/
    target: "..."

The config file is parsed as YAML, and a 067 unquoted _will_ be parsed as a
number.

I can even change feed2imap to handle receiving numbers as the feed name by
converting them to strings, but I can't stop the YAML parser from doing the
octal to decimal conversion for example.
