You can view my notes at azcrumpty.mooo.com/, which only works if you have IPv6 setup and working. If you don't, you may use a gateway azcrumpty.mooo.com.ipv4.sixxs.org/.
My ISP doesn't block the smtp port, 25 on IPv6, so I can run my own mail gateway. If your provider can send to IPv6, which I find many don't, you can email me at email at email@example.com. The folks at FreeDNS have graciously allowed my to piggyback on their domain.
I will take this server offline after about a month since the computer it runs on is actually my Linux Mint laptop, which I would like to use for laptop use. It is virtualized, so I can move it should I wish to keep it turned on.
