ISE SMTP SERVER

[prathyusha]

Hello friends,

I am trying  to send the email to Guest Users with their credentials to login to the Guest-Wifi. Our SMTP server only supports TLS Port 587, but looks like ISE still using the non encrypted TCP/25. Is there any other way we can make this work.

How to add the Authentication for external SMTP server on ISE?

Secure SMTP was a feature just introduced in ISE 2.7. You will not be able to use secure SMTP in 2.6 or older since it does not exist.

2.7 was just released, I would be very cautious before moving production to it since little is known about its general stability.
