Thus spake "Jack Bates" <jbates@brightok.net>
After the renumber, I'll only have 69/8 space, which means all critical services such as my mail, dns, and web servers will all be affected. I hear it now. "I didn't receive mail from so and so!" I check the logs and don't see an established connection to my server. So, is the problem that the far mail server lost the message, the user emailed the wrong place, or my new IP addresses weren't accessible by the far mail server or the dns servers that it uses?
There's several BCPs that tell you to have at least one DNS server and at least one unfavorable MX off-site. If you did this, your mail would be safe, albeit a little slow from misconfigured sites.
