I need a way to automate emailing of snort alerts
 

I am running Snort 1.8.7 at one of my customer's premises. The network administrator is not knowledgeable in security related issues. I would like to know if there is some software or plugin that I can use to automatically email Snort alerts to my Inbox for realtime analysis and assessment. Any help would be greatly appreciated.

There are many ways, I just throw one, and you'll see somebody will jump with anothre one and so on. You can setup a cronjob to mail the alert file to you, i.e.
30 * * * mail you@yoursite.com < /path/to/snort/alert
