Send Email task failure Error: 4.4.1 connection timed out

Question

I use an SMTP connection manager and Send Mail task to send emails to customer approx 5000 emails.

The SSIS package runs successfully when the elapsed run-time for the package is less than 10 minutes.

The Send Email task fails because the SMTP server closes the connection after 10 minutes.

An error occurred with the following error message."Service not available, closing transmission channel. The server response was: 4.4.1 Connection timed out.

Any suggestions to fix this issue.

Hi @Arnya,

What smtp server are you using?

If you are using Exchange server, you may check it out here.

If you are using your own server in your company, you may look for help from your technical engineers.
