Insufficient system resources

Question / Problem

I am evaluating this product and am having trouble getting it to deliver email. It keeps giving an error that the SMTP server is reporting insufficient system resources. This of course sounds like a server problem, but this is a test environment with only one mailbox running and there are plenty of resources. I am running this on Windows2008 and Exchange 2007. Any other possibility for what could cause this issue?

Answer / Solution

This error message is reported by the Exchange Server to SmartPOP2Exchange when SmartPOP2Exchange tries to sent the mail to the Exchange Server.The Exchange Server 2007 needs much resources (like 2GB RAM etc.) especially if you haven 't installed the SP1 the ExchangeServer 2007 requires 4GB free disk space:See https://exchangepedia.com/blog/2008/02/exchange-server-2007-sp1-most-obscure.html
