SSIS package in which i am using Send Mail Task Plus to send email via (email-smtp.us-east-1.amazonaws.com). My package is running fine on testing server but when i try to execute it on dev server it shows exception. I also tried to "telnet email-smtp.us-east-1.amazonaws.com 587" on CMD but not connecting via telnet on dev server. It seems like "email-smtp.us-east-1.amazonaws.com" not accessible from my dev server. Port i am using is 587 and same port is working fine on my testing server. Please suggest what can i do to fix it.

Expanding the comment as an Answer to include screen shots:
In Windows Server 2016, the application is called
Windows Firewall with Advanced Security(available in the start menu). Other Windows version would have a similar app.When you launch it, you would get a screen similar to the below:
If you have "Firewall is on" message, get in touch with the System Administrator responsible for this server and provide all these details.
The firewall can be configured to allow your mail connections.
Additionally, some of the anti-virus products (e.g., McAfee) can be configured to block access to send mails. In this scenario, your anti-virus log would have some details if it is blocking your connection. In this case, also go to your System Administrator to configure it to allow mails from your application.
