Multiple domains and Virtual Servers
|
|

| Hi..! I'm new to networking / SMTP / DNS etc.. My system is Windows
2003 Enterprise with Active Directory.
I have Default SMTP Virtual Server configured and it seems to work
fine. I can successfully send e-mails to local POP3 service accounts
and outside also (public internet e-mail accounts).
I want to use ANOTHER local domain, such as myotherdomain.com to send
mails also.. I created a new Virtual Server by right-clicking -> New
Virtual Server. Configured with same IP address but listening on port
2525. Relay is permitted for my local IP address. New domain is:
myotherdomain.com
I CAN send from myotherdomain.com to myoriginaldomain.com, but I CAN'T
send e-mails OUTSIDE the LAN. The message appears in DROP folder.
Here's the scenario, simplified (hopefully):
*** user01@myoriginaldomain.com -> user02@myoriginaldomain.com
WORKS
*** user01@myoriginaldomain.com -> user@microsoft.com
WORKS
*** user@myOTHERdomain.com -> user02@myoriginaldomain.com
WORKS
*** user@myOTHERdomain.com -> user@microsoft.com
DOESN'T WORK!!!
What am I doing wrong here?
I don't know if it's necessary, but I also created a new Forward Lookup
Zone in DNS (myOTHERdomain.com). I have don't know what an MX record
is.. I don't have it.. do I need it?
Relay is enabled for my local IP address in SMTP configuration.
Please help!!

You should not need another virtual server to send from another domain.
Your mail client controls your From: field. As long as the first
SMTP virtual server allows you to send (by IP or using auth) you can
send as either user@myoriginaldomain.com or user@myotherdomain.com.
Receiving is different. You will need another MX record to receive.
But you can still use the same virtual server to receive.
