Whitelisting problem

IBM is a partner of ours so I have whitelisted ibm.com

But now some spammer is forging both the envelope and header to look like it
cam from ibm.com

The spammer appears to be creating random addresses ending in @ibm.com

Is my only choice to remove ibm.com from the whitelist?
