Starting last week we have been seeing a lot of bounces like the one
below from two sites. The problem seems to be DNS but all machines at
both of the sites are browsing OK and mail gets to us with no pronblem.
This is happening with several mail servers not just with AOL. The only
thing common to both sites is their reverse lookups are broke - but
would that cause a host lookup error?
Thanks in advance
