I updated to the 3.10.26-1 build, so not much uptime. Also, I don't have my
IPv6 hurricane tunnel active ATM.

I'd added this into my /etc/firewall.user. I'd be happy to work on adding
it into the official script if you would like. I'm a sysadmin, what
development skills I have are in scripting.

If it's scripting and web server config, I'll work on this too.

This I can work on now, if you like, I can spin up a Digital Ocean VM that
should be able to run a mailing list with no problems. Getting Postfix
setup should be a snap, I'm not sure what else is needed for the mailing
list, but we can discuss it off the mailing list. Did you want a new name
or keep huchra for the VM? Once it's up, getting a list of needed software
from huchra, certs, and the data can be synced over, do some testing, then
the DNS A and MX records can be updated.
Hmm, just saw that Digital Ocean still doesn't have IPv6 yet. Will that be
a problem? Any other suggestions for hosting it? I've used them for several
little projects, they have a good interface and rates, IMHO. Thanks.
