Hi All,

We identified the issue with ssl certificate which was expired on Mail server.
issue was resolved after replacing ssl certificate with new certificate.

We have another solution also for this issue, please select SecureConnection = None in the properties of Send SMTP Mail Message activity. but, using this option we are bypassing ssl encryption. am not sure this is recommended for production environment or not.
