No, the other way around. a "not" dropped out: :(
s/does answer on IPv6/does not answer on IPv6/
When it carries an AAAA record but does not answer on IPv6, the attempt to connect via IPv6 will fail and only after the attempt times out, the mailer will fall back to IPv4. Not fatal, but mildly annoying.
No happy eyeballs for Fidonet mailers yet. :-) Coming to think of it, I don't think we'd want that. It will speed things up in a flakey IPv6 environment, but it will complicate debugging..
