"Exception reading response" Error with SMTP Connector

I came across the following issue on the SMTP Connector after making the "Non Recoverable Error" to a "Recoverable Error" in the <ReturnCodes>.

The Error was gone, but sending the mails was taking a log time to got out.
After investigating the issue. I released why I got the issues.

In the SMTP connector the FromAddress is <sxi:FromAddress>noreply@ourservicedesk.com</sxi:FromAddress> and in the Data Definition the "From" was "xlayer@Client.co.za" clearly not the same.
I have removed the Field "From" in the Data Definition, that fixed the issue.

Log with ERROR:
06:37:31.495 - WARN  - Non Recoverable error detected but will reset connector and retry operation one more time

I don't think you need the "From" in the Data Definition, if the FromAddress is specified in the SMTP Connector.
