E-mails are no longer sent to recipient(s). The SMTP settings in CAPC are correct and sending a test e-mail using telnet from the CAPC server works OK.

The cause in this example was the CAPC server was unable to resolve the fully qualified host name. From the DMservice log (CAPC server) we can see the following error:
ERROR | EmailJobTaskThreadPool-Thread-285 | 2019-10-09 08:00:48,858 | com.ca.im.portal.dm.scheduling.email.EmailJobTask
| Error sending email: myserver.domain.com
As we can see here CAPC is unable to resolve the fully qualified host name, myserver.domain.com.
When you run ping hostname only it works but ping myserver.domain.com fails.
