Hi Susan,
The records that Richard was talking about was not that of your actual
mail, but the Domain Name Service (DNS) records required to find the
destination server and for that server to look up your server to verify
that the mail comes from a valid address. I recall a discussion earlier
this month about the root DNS servers being updated to a new version of
DNS software that would increase the size of the DNS records. This would
then take a while to filter through the "tree" of DNS servers and
eventually software that could not handle these larger records would fail.
I hope that this sheds some light.
