Thanks  Derek. Your patch worked for me. I had already disabled IPv6 via
sysctl and took all IPv6 addresses off my interfaces. The about:config
solves firefox, but mutt and ssh were still a problem.

I'm a bit surprised at some of the suggested workarounds. I wouldn't
really blame the resolvers - things shouldn't be doing AAAA lookups if
ipv6 is disabled in the first place. It might be possible to blame the
authors of virtually every network-aware app, but that isn't realistic.

Most of us running ubuntu in corporate networks with broken Microsoft
resolvers are doing so completely unsupported. If you open a ticket,
you'll be lucky if ignoring it is the worst that happens. More likely
you'll be told to use a supported environment and just give them another
reason why linux users are an expensive problem. "Go fix your resolvers"
is just not a reasonable response. Using other DNS servers doesn't work
in this case either, because they don't have access the intranet zones.
