How to send workitem to other mail servers like Gmail, Yahoo, etc..

Hi All,

I have a requirement, when a PR is created a notification mail has to be sent to the MS-Outlook and workitem has to be send to the sap inbox of the approver, and an workitem has to be sent to the approvers gmail or yahoo etc.. mail server, from there the approver has to approve or reject the PR.

I am surprised is it possible to send a workitem kind of thing to external (eg. gmail or yahoo) mail server from where the approver can approve or reject the PR.

Kindly help me in this issue.

Thanks and Regards
