How do I disable email address format checking on EAP7 for OpenShift?

Issue

• How do I disable email address format checking on EAP7 for OpenShift?
• javax.mail.internet.AddressException is thrown as below when I specify .test@redhat.com or test.@redhat.com in a mail transfer code. Prior to JBoss EAP 7.2.7, no exception is raised. How can I disable the checking process?

Caused by: javax.mail.internet.AddressException: Local address starts with dot in string ``.test@redhat.com''
