Thank You, Mike Katz mailspect.com
If anyone is looking for a way to intelligently associate emails with
Salesforce.com opportunities or cases from Postfix we have developed
something that can do this in real-time using web services. We need some
testers so please contact me if this sounds interesting. It is all baked
and working. Besides SFDC we can easily connect Postfix email into any
web services application if it has a suitable api.
