No, I think that's not it. Rather:

- unparenthesized token: looked-up host name.
- parenthesized token: HELO string (with brackets if IP).
- bracketed token: connecting IP.

The third one is always present; either of the preceding two may be
absent, but they are always in this order.

The looked-up host name is missing if the IP doesn't reverse-resolve.

The parenthesized token is absent if there was no HELO (or empty?)
