Hi Bill,

I called the hosting provider and finally got help from them. They suggested that the IP security was the problem. I went into the Local Security and Policies and changed the Packet Filter to not 'Block All'. Generally, the hosting company does not give help in Server Administration issues as they typically say consult your own Administrator.

Thanks for your input and suggestion.

Best regards,

Bob

>>I have a dedicated server plan with a third party and it hosts web applications I have created. In addition, I have jobs that run that send emails from this server. I am using another third party for sending emails and use the .NET mail class to send emails. However, the third party email provider requires Port 587 to be set for sending emails. I have set this port in the code but I am unable to connect to the smtp server. I am assuming it is because port 587 is not open on my dedicated server.
