## Solution

Dynamic ID with SMTP server that requires user name and password for authentication is supported only from R80.20.

* Authentication without TLS (will default to port 25):  
  mail:TO=$EMAIL;SMTPSERVER=smtp://**username** :**password** @**smtp.server.address** ;FROM=**sslvpn@example.com**;BODY=$RAWMESSAGE

* Authentication with TLS on default port 25:  
  mail:TO=$EMAIL;SSL_REQUIRED;SMTPSERVER=smtp://**username** :**password** @**smtp.server.address** ;FROM=**sslvpn@example.com**;BODY=$RAWMESSAGE

* Authentication with TLS on default port 465:  
  mail:TO=$EMAIL;SMTPSERVER=smtps://**username** :**password** @**smtp.server.address** ;FROM=**sslvpn@example.com**;BODY=$RAWMESSAGE

* Authentication with TLS on custom port:  
  mail:TO=$EMAIL;SSL_REQUIRED;SMTPSERVER=smtp://**username** :**password** @**smtp.server.address** :**port** ;FROM=**sslvpn@example.com**;BODY=$RAWMESSAGE

**NOTE** : Username and Password can not contain special characters like the **@** symbol. They require to be URL Encoded. For example if the username is sslvpn@example.com the string should be sslvpn%40example.com.
