Hi @Gonela

Nagios XI handles email for contacts who are XI users and contacts vs those who are contacts only. In short Nagios xI, uses sendmail for contacts who are not XI users (core contacts), and php mailer, which supports SMTP settings, for those who are both XI users and contacts. It is likely your having issues with using sendmail.

From Admin > System Config > Manage Email Settings > General Mail Settings, you can turn on the Debug Log for and view mail logs for any errors.

If your having issues with Sendmail, you can configure your (Nagios core) contacts to use the Nagios XI php mailer settings, and we have a tutorial on how to do this:

Please let me know if your able to get it resolved.
