SMTP server configuration in ISE

sujanyakj — Tue, 10 May 2022 07:44:32 GMT

I am trying to configure SMTP in my ISE 2.4 box.

I was able to find only the smtp server option, not getting test connectivity setting and also there is no place to provide the smtp port details.

Is this the default behavior of ISE 2.4

AFAIK this is the default settings for 2.4. I know with later versions you can set port, connection timeout, encryption settings, and authentication settings. HTH!

ISE 2.7 supports Secure SMTP with Username+Password and custom ports and Test Connection like you are asking.

Hi @sujanyakj - default is TCP/25

Yes - a send email would be a nice feature in older ISE releases - we've been dreaming of this for years 🙂 Time to upgrade to 2.7 ;-0😉

You can test email server in two alternative ways

1) Go to Guest Portal, Portal Page Customization, then scroll down to Notifications > Email and then you'll see a "Send Test email" link.

2) Go to Admin > System > Settings > Alarm Settings > Alarm Notifications (put in an email address and generate some alarms - ISE will send emails)
