SAP will not send email out. In looking in the outgoing emails you see that they are not being sent out and have a red X.
The error on the server will include:

System.IO.IOException: Authentication failed because the remote party has closed the transport stream.

The work around: Download the attachments to your computer and then send them out through you email as an attachment.
