Emails not sending with timeout error in logs

System.Net.Mail.SmtpException: The operation has timed out.

• SaaS

• Tyler Forms

• ReadyForms

• DocOrigin

• Port 465

Port 465 is depreciated, and is subsequently blocked as a security measure on some hosted servers. 

Use Port 587 as an alternative. 

This is an uncommon cause for the timeout error. Other causes of this error are rate-limiting and authentication failure.
