Open Source Document Management System | OpenKM

We are using OpenKM 5.1.9. In which we have User Groups for Sending mails and Authorisations. If the user groups are containg any invalid e-mail id, System is not sending mails to other mail ids even in other groups also.

Kindly help us to resolve the issue.

Thank You
Venkat

I have added the issue at http://issues.openkm.com/view.php?id=2222

Which kind of invalid e-mail? Can you post an example (as much detailed as possible) to reproduce the problem?
