MSMAIL --> Exchange Migrations w/ Third Party Internet Email Provider
Posted on 2005-04-11
Looking for some opinions from exchange experts.
currently my company uses MSMAIL (yes, Microsoft Mail) running on a netware server to hand its in-house email. the company currently uses about 75 in-house mailboxes. the network infrastructure is as follows:
2 Windows Server boxes (1x 2003, 1x 2000)
Single windows domain (matches *.com internet address)
1 Netware 5 boxes (file server)
10/100 LAN architecture throughout
DHCP/DNS/AD provided by Server boxes
Netware only for file serve, with MSMAIL currently on the system.
Internet email provided by third party ISP
Full T1 internet; Vina router acting as primary gateway with no respectable hardware firewall solution.
Office 2000 on all clients. All but 3-4 clients are 2000/XP pro, which should be there by rollout stage.
Office 2003 licenses have been purchased for sometime, but because MSMAIL isn't supported, we haven't rolled out.
The plan is to add a second Server2k3 box (third Server box). 4x73GB U320 RAID5 array. P4 2.8GHz Prescott. 1GB ram. This box will be solely for exchange, maybe with DNS running. We have a full T1, but because our firewall solution is basically non-existant, we DO NOT want to provide internet email with this box at this time. We just want it to do in-house email, and outsource our internet email and website to Dreamhost. Currently, everyone's mail is kept in PSTs on the netware server. Since the mail system has been in service for 5+ years, the PSTs have gotten rather large and constantly need repair.
What is the best way to proceed with our migration?
My back-of-the-envelope plan goes something like this:
1. Setup and install exchange box onto the domain.
2. Enable everyone's email boxes in AD
3. Go client to client and install O2003 (maybe look into centralized rollout w/ windows?)
4. Add everyone's exchange box to the outlook profile. Move PST contents to exchange account
5. Add an internet mail account to each client
Any suggestions would be appreciated. Don't bother questioning the decision to go with exchange. Its already been bought. But everything else is on the table.
What is the best way to use exchange for in-house email while using third party for external? can i configure exchange to accept all email, but forward everything outside our domain on to our third-party SMTP server and pull in everyone's incoming internet mail with a POP3/SMTP connector?
