I am getting an error trying to send an email but the error source is listed as "System". I would expect the error source to be the SMTP server, yet there is no record of SMTP servers returning an error like this. So WHO is "System"?
There is a system stating that another party has closed the transport stream. How do I find out who the system is and who the party is?
<Message>Authentication failed because the remote party has closed the transport stream.</Message> <Source>System</Source>
