SBWP - mail was not sent to distribution list
I have created a batch job in which I have put a distribution list. This will send a mail to the Business Workplace (SBWP). The job ran sucessfully during a month, but since yesterday, the mail was not sent to the people in the distribution list.
I have checked the job and the distribution list is still connected (as express delivery).
What can be the cause?
Thank you for your feedback.
