Release 0.18.1 highlights:

# Fixed

- Startup error if `log-file` directory does not exist.
- Aerc is now less pedantic about invalid headers for the maildir and
  notmuch backends.
- Error when trying to configure `smtp-domain` with STARTTLS enabled.
- `smtp-domain` is now properly taken into account for TLS connections.

Thanks to all contributors!
