SAP Sourcing Problem with some specific mails

Hello,

Im testing emails notification in the MA, but for some particular actions mails notifications are not sending:

1. Version share with supplier

2. Contract document new purchaser version

3. Contract document new supplier version

For the others mails notification everithing is working fine.

I already activate daemons option, asigned host name in cluster and asign time zone property, is there something else that I have to be aware?

thanks in advance

Regards
