Whitelisting problem

[Matt Kettler]

hmm why not:

whitelist_from_rcvd *@ibm.com ibm.com

The second part of the command does not have to be a complete server name.
Just a substring of it. So if any of the mailservers are reported as
(something).ibm.com in the received headers, this will have the same effect
as your "lookup" feature.
