Please help.

Having issues in trying to test send notification.
Used "send test notification" and everything seemed to work in the gui.

Checked /var/log/syslog and below is what i see:

You have a network problem. Appears multiple times in your logs. Solve the port 25 -> external IP address problem, and your email will work. Internal testing was likely done via PHP sendmail, not SMTP.

It looks like your postfix is configured to use SMTP as well, which isn't something XI would do. When using 'Manage Email Settings', we either let you specify a SMTP server there, or use sendmail directly. I would review your settings as @eloyd mentioned.

thanks everybody; it has been fixed.

Awesome! Going to close this out and mark it as resolved.
