spam as an operational issue

A dial-up customer complained about bounced messages from Sprynet.
I think their explanation may be of interest to Mr. Dean "Spam Costs Next to
Nothing" Anderson and a few others.

Note that sprynet runs four mail servers round-robin.

Hi,

We are having great difficulty connecting to port 25 of your mail
servers.
We are usually getting 'connection refused' messages.  Our mail server is
mail.webkorner.com (207.53.76.15) and has all proper dns entries,
including
reverse dns.  Are you having any system difficulties?

Thanks,

Matt Sommer
Sysadmin
