Checking on DNS secondaries

Sat May 21 12:49:25 PDT 2011

ps. I run my lanning.cc email server from home on my comcast business
cablemodem.
and I get this "(reason: 550 5.0.0 <baylisa at baylisa.org>...
comcastbusiness.net needs a working abuse contact to send mail)"
for both baylisa and svlug.

I run the script below (that I originally created to monitor slave
replication.)  It can be run via cron to give you a daily/weekly report.
