No, the key message is the previous one, the server's greeting:

  [18:14:17] POP3< +OK GMX POP3 StreamProxy ready

No timestamp in the greeting, nothing Sylpheed can return in the
authentication handshake. GMX's server currently does not support APOP,
or else it would send the timestamp.

I don't think so. Rationale given above.
