DNS Upstream refresh

After an, otherwise, succesful migration the MX record of the BIND
nameserver ended up like this:

domain.com. IN MX 10 mail.domain.com

instead of:

domain.com. IN MX 10 mail.domain.com.
(that dot at the end.....sigh)

Now I need to refresh the dns information upstream cause some MX
servers out there send mail to
mail.domain.com.domain.com instead of the correct address.

I've corrected the typo, lower the refresh to 5 minutes for the master
zone, tunred on notify for the zone. Is there anything else I can do
to speed up the update?
Specifically is there a way to access an internet dns server and
specifically tell it to retrieve the new zone information?

thx in advance,
bill

No, you'd have to get the whole Internet (or at least everyone who sends
you mail) to drop their caches.

For future reference, drop your TTLs to 5-10 minutes a day or two before
making changes like this, to mitigate the effect of errors. Once you are
satisfied everything is working, raise them again.

You could create an A record mail.domain.com.domain.com with the address
of your mail server. As long as your negative caching TTL is sensible (it
should be around 10 minutes) this should get your mail flowing again.
