mail between 2 domains physically on the same LAN.

Hi

Iam maintainaing 2 domains physically on the same LAN.

Each one works fine, users aaa@domain1.com sends can send mail to user1@domain2.com, but the mail routes externally and takes a minute or two to arrive.

can  i route mail from one domain to another like internal mail from user1@domain1.com to user2@domain1.com so mail between autonomous domains is faster?

Domain1 is win2k3 and domain2 is win2000

Thanks

There are 2 ways that I can think of doing this, first would be to setup DNS entries on your local DNS servers for each domain, and then configure MX records pointing to the LAN addresses.

The other would be to use an SMTP connector for these domains in exchange to redirect all mail for those domains to the other server - this may be a little more complicated to setup -> http://www.amset.info/exchange/smtp-connector.asp

I don't think that one is better than the other - DNS will have to be managed well (if you change DNS on the public side (new web server) you will need to make sure the internal DNS is configured the same - the SMTP connector will be a little more complicated to setup, but once it is done, it is done.

You should be able to setup a DNS zone for each domain on the other DNS server.
1) On domain1 open DNS manager
2) Create a forward lookup zone for domain2
3) Create an MX record
4) Create an A record to point to the correct internal IP address
Repeat this for domain2

The SMTP Connector method is the best way of dealing with this.
Simply create an SMTP connector that uses the other server as a smart host and enter its IP address in [ ]. On the address space tab enter the domain name the other server is responsible for. Repeat on the other server.
While the DNS method works, it can cause problems. You have to replicate the entire DNS zone internally, which could include things like the host names for www and anything else in the domain. The SMTP connector method is used for email only.
