cannot send alert email
I installed ServerCheck STANDARD version, and set the rule to detect TCP port if web server is running.
When webserver is down, I can see the "STATUS" change to red "DOWN" flag, that's ok.
But the problem is I cannot receive all alert email, sometimes I got email sometimes doesn't.
I have set the internal mail server, but it looks not work stably. I want to know how I can set and test through external SMTP server, for the first time I launch ServerCheck program, it gives me the option to setup email, but later I cannot see this prompt. Is it possible to detect and test email server before I click "start monitoring" button? Thanks.
