Ok, sorry about that.
Here are more details. We have a completely new machine that's got
the following specs (sorry I put the wrong HD size down before):
Pentium 4 processor (don't remember the Ghz, think it was like 2.8 or 3)
2 GB of RAM
2x 160GB Hard drives setup as RAID 1 for 160GB of space
Latest Debian installed
Currently it's not online, but we can probably get it online
available via SSH within a day or so.
Work on it pretty much came to a stand still as people just didn't
have time to work on it. I got the initial install going, Greg did
some work on mailman, but that's about it. I'm now dealing with full
time job, grad-school, and a sick 6 month old.
I've been real slack on the leadership of this project, that's my fault.
We need someone (or several) who is experienced or at least confident
they can figure out how to do the following with email:
Setup Postfix with Virtual Domains to host multiple email domains,
and make sure it works with mailman
Setup dovecot or courier imap/pop3 with SSL encryption, no
unencrypted email connections for email access
Setup https access to SquirelMail for webmail access (squirelmail
will basically use local imap connection)
I forgot I actually have some nice how-to's on this bookmarked at
home, I can send them later. Uses mysql to handle account management
(which I do on my production server).
Beyond that we also need to setup DNS services on this machine, to
match what calypso currently handles.
Once all that is done, we can then schedule a maintenance window
where we can migrate the old data off of calypso.tux.org onto this
new machine and let it become the new calypso.tux.org. This first
migration would consist of mailing lists and DNS.
After this swap is done we can then schedule a second maintenance
window to migrate all email services from gywn to calypso.
Calypso will not have shell account access to users, those users who
wish to have a shell account to access email will continue to use
their current shell account and setup their terminal email program to
access email over imaps or pop3s on calypso. This may be a slight
inconvenience, but modern software regardless of it being command
line based or GUI should be able to handle this. The reason for this
is we want this machine to be super stable and secure. Only
administrators should have shell access, we don't need any rogue
processes by accident.
Anyways, that was the plan that I haven't been able to implement.
I need active volunteers who are willing to do the work. I can
provide "some" help and guidance, but my clock cycles are pretty well
