Yes, I have advised them of the costs and they say it is not object, I have
cntacted their ISP and they do not offer vacation/away/out of office
messaging
If they don't already have a DOMAIN, then I would suggest SBS 2003, it's a
DC, Exchange 2003 server, and is a all-in-one solution. Just make sure
that you purchase AV software that is Exchange Aware for the SMTP
filtering. I use Symantec Mail Security 4.6 on all Exchange servers and
set it to block spam, do RBL, remove attachments that should not be let
in, and also check all in/out bound email for viruses.
You also need to backup your exchange server nightly, I think that E2003
Standard is still limited to 16GB store size, so a cheap SCSI 40GB tape
drive will more than do for the Exchange side.
One thing I've seen is that Exchange loves memory. We have clients with
as few as 8 users and the server seems (running Windows 2003 Standard and
Exchange 2003 Standard - not SBS2003) to have a sweet spot of 1.5GB for
RAM (and Exchange is the only thing that server does).
Do you have a firewall appliance - something like a WatchGuard Firebox
III/700 or other vendor - one that does SMTP filtering can be a blessing,
it blocks attachments based on file extension and mime types, and it does
it before the Exchange server sees the email - also blocks/removed bad
headers and such...
They will also need at least 1 fixed IP address and also DNS entries, and
you should start by making sure that their ISP is not already on a
black-list. Also, some ISP's block SMTP except to their own email servers
and others require a Business account in order to run your own public
servers, you might want to check with the ISP first.
