We are using sendgrid to send the emails to customers. Just yesterday, got the issues and when analyzed log, we could see 221 and 421 error with sendgrid.

The issue was the slow connection with sendgrid and due to the same, it return the error. Checked ping and tracert to smtp.sendgrid.net and getting very slow response.
