What is the error message that you get?

tsNet will try re-use an existing connection if there is one available, 
so this first example:

Indicates that there was no existing SMTP connection to the server, so 
it needed to establish a new connection.

Where in the following example:

This indicates that tsNet found an existing SMTP connection to the 
server you are connecting to, so could just send the message across the 
already open connection.

You can add the "no_reuse" element with a value of true to the settings 
array (last parameter to tsNetSmtpSync) if you want to establish a fresh 
connection for each e-mail that is sent rather than allowing tsNet to 
reuse an existing connection.

Hope that helps,

Charles
