You can whitelist users or entire domains from the rDNS check in your access file using Niel's hack.
I would rather whitelist a single domain than turn it off entirely if you had been using it since december with only a little fallout. Add: rdns:1.2.3.4 OK rdns:@somehost.com OK to whitelist for solely rdns, it will also honor regular whitelist entries with no left hand side token: 1.2.3.4 OK 5.6.7 OK 5.6 RELAY All of the above exempts those IPs (or domain names) from rdns checks. As long as your users are not completely virtual (i.e. this box does mail routing only) then you can also do this on a per user basis.
