Converting from Sendmail to Exchange 2000 for email
Posted on 2005-03-07
I am preparing to replace Sendmail with Exchange 2000 in my Windows 2000 Active Directory Domain. For the purpose of this scenario, I’ll call our domain domain.org. Sendmail is currently configured on a unix box (unix.domain.org), which delivers mail via a dialup-link to a smarthost provided offsite by our legacy database vendor.
I have 2 domain controllers (dc1.domain.org (primary) and dc2.domain.org), and a third Windows 2000 server (mail.domain.org, not a DC) (twin Xeon 2Ghz/2GB RAM/80GB) that I will install Exchange on. I have already run forestprep and domain prep on the (primary) domain controller.
I would like to accomplish this without having to change my organizations email addresses, if possible.
I have a static IP and am running NAT on my firewall.
What MX records do I need to specify, and how to I make these changes? Through my ISP? Do the new MX records supercede and/or replace the old ones?
Is there anything else I need to do before installing exchange on mail.domain.org?
Can I keep my existing email addresses?
I would like to use OWA in house, and add web access later, so this would eventually be the back-end server - are there any special configuration issues here?
What other potential obstacles do I need to be aware of?
I am planning to make this change on a weekend to keep disruption to a minimum.
In case you’re wondering (I’m sure some of you are), I’m using Exchange 2000 because we already have all the necessary sw and licensing (this has been a work in progress), and there is no money in the current budget for 2003 – maybe next year.
Thanks in advance for your feedback.
