There have been few queries from clients asking if it is possible to import work items by e-mail into IBM Rational Team Concert. This is a somewhat complex topic as it isn't currently supported, but there is a potential work around. Let's take a look at the information:
A. There are the following properties in Advanced Properties page of the CCM application in RTC:
Online Help for this says: "A periodic task runs on the server that checks for mail received for work item creation. This property specifies the time in seconds between runs of this task."
B. Here is a brief on this feature from Jazz.net wiki
C. However, there has been an RFE on this already and you might want to add a comment here with your additional business justification. The details, along with a business justification should add more weight to this RFE.
I hope this note adds to the links above on this topic.
