[SAC] Moving the mail server off of osgeo1

[Howard Butler]

Alex (and others with mail migration experience),

I would like to spearhead the effort to move our mail operations off of osgeo1 and into a virtual machine inside of OSL.  I think the timeline to have this done is by Oct 31st.  

Steps to implement:

1) Determine where things are going to land. I will coordinate with Alex on this one.  I presume we'll put it on one of the existing VMs and cook up backula scripts to keep things together
2) Determine what things to migrate
	a) mailman
		i) archives -- do we run apache on our mail server, or serve these out some other way?
		ii) mboxes
	b) aliases
	c) user accounts?
3) Notify and plan for an outage -- mailing lists are the one resource that everyone seems to interact with OSGeo infrastructure with. Mail server migrations are often painful. We should set the expectations for our users that things may burp a bit during the migration.
4) Execute migration on Oct 29th-Oct 30th
5) Pick up the pieces.

If anyone has moved a big mailman installation from one server to another, I'd be interested to hear your experience. If you have ideas how this should go, I'd also like to hear them.  I'm willing to do the legwork to make this happen, as lack of mail migration makes for a convenient excuse to leave the Drupal installs alone too. Those (and their databases) need to be moved soon too.  We need to get out of Peer1, there's just not the money for it.
