comment Disable local root login, permit root login over ssh
do this and encrypt all volumes on the disk and you'll really annoy whoever is trying to get in as it won't come up correctly without you entering a password on boot. So long as someone else has physical access to the machine you can never guarantee security however every little bit helps. If you are going to try this have good backups however as recovery will be difficult/impossible if something goes wrong.

comment Preferred mail system/server for a company?
I've been both a Lawyer and a Sysadmin and can tell you professionally that many of the hosting enviro's wouldn't cut it. While some of it is FUD in the event of a privacy breach you could be run into serious issues depending on you jurisdiction and "it was our hosts fault" won't save you. Specific areas of law also are subject to greater privacy requirements and as such would not be suitable for outsourcing in this manner as you lose control as to 3rd party access. You also open yourself to issues if your host is subpoenaed and/or hands over your info, too much risk. (Not legal advice etc)

comment Preferred mail system/server for a company?
That entirely depends on your business; if he is talking about a law firm with 20 people it could be criminally negligent to have your email hosted elsewhere. If your bouncing huge attachments internally a n outsourced vendor may not permit that. If your internet connection is intermittent you may need a cached offline solution with a local server. It makes plenty of sense for a lot of small companies without BES to host mail internally.

comment Amavis and Postfix VirusMails
it looks like it is in the CentOS packages for 2.5.3-2 and I have 2.5.3-1! Just unlucky but pushing the mails to another system running a more recent version and unfreezing them from there with that command has done the trick!

looks exactly like what I'm looking for however the command doesn't seem to exist on my system. amavisd-new-2.5.3 is the running version.

comment Using Exchange but not storing email
Oh yeh, thats probably the easiest; just set up the server; create your user accounts and then use a program like fetchmail running on a a linux box to pull down mail, I know exchange used to have a tool inbuilt but i'm unsure as to its status. Google "Exchange IMAP connector" should start you down the right path.

IMHO if you can drop exchange onto the AD controller (not best practice I know but assuming you don't can't run up another machine to take the role) set up 2 or 3 users and test. What you want is possible (but not as clean as an all out exchange enviro). User testing is the only thing that will tell you if your users are ok with the way it works. Alternatively you could go full exchange and use a tool to download all mail from their IMAP boxes to the exchange server and leave a copy on the mothership's server.

comment Using Exchange but not storing email
Exchange functions with SSO on their domain login; if they are authenticated on the domain server for their workstation then they are authenticated to the exchange server (assuming your desktops are connected to the windows 2008 server) so no "second" account there. The calendaring would only work internally and I would guess that Outlook would default to using exchange to transport those messages. However if an external appointment request came in via imap it would end up on the exchange calendar as it's the default.

Doesn't indicate the "mothership" uses exchange, they may well not.

comment How do I best archive VMWare VMs for reuse?
I've done this and it works but if your xfring a lot or want to do it in a more automated fashion I'd recommend enabling SFTP on the ESX host and using either WinSCP or SFTP to pull the images down. I've found it faster and more reliable.
