Am trying to create a service utilizing pub.client.smpt to
send email. Email has been setup on the server and works
via the unix command line. Yet when execute the pub.client.smtp built-in service, am getting the following error:
com.wm.app.b2b.server.ServiceException: javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: 451 … Sender domain must resolve
So, the UNIX box on which Integration Server is running can send email via command-line but not using pub.client.smtp?
Are you sure that you have the proper DNS settings for your mailhost? As a security check, some mailhosts will perform a reverse lookup and if the IP address can’t be resolved, a 451 error is thrown. If this is the case, check with your server administrator.
