Community Support for OpenDocMan (Deprecated)

I installed v1.2.6.2 OpenDocMan, when you run the checkin or checkout the email is not sent to members of the workflow. Neither for nor a member to various members.
In short, sending e-mail fiunciona not.
The other features of the software are functioning normally and not yet implemented in our Company for failing to send email.
Please help me solve this problem.
I thank you.

I think the only time emails are sent is when a file is authorized or rejected. A feature request exists to allow for emails after add or check-in
