Change the SMTP and POP3 Name in Exchange 2003

Hello I am new to Exchange and need some help please.

I have a client that when they setup there exchange and IIS they used the name www.fc2h.com

So now if I was to telnet to the server IP port 25  the SMTP server responds back as mail.fc2h.com

The client no longer has this domain they have a new domain now called www.focuscareusa.com

So if you were to ping mail.fc2h.com it no longer will resolve.

The new domain is focuscareusa.com  

The MX record mail.focuscareusa.com resolves fine.

So How do I make the change in Exchange so that the SMTP and POP3 will respond back as mail.focuscareusa.com and Not mail.fc2h.com

Hello I made this change smtp virtual server\delivery\fully-qualified domain name change the name
and still can not recieve email to my new domain name.

I had  the old domain set to mail.fc2h.com and changed the domain to mail.focuscareusa.com and restarted the SMTP service and still can not send email to user@focuscareusa.com

Can someone please help me.


Thanks

Add a recipient policy to exchange with the domain suffix focuscareusa.com, apply it to all users who need that address (just use the one filter called, "users with exchange mailboxes).  This will give everyone an e-mail that ends with focuscareusa.com.  Then you have 2 choices, you can masquerade the domain name in IIS's SMTP configuration under the delivery tab, add the domain name to the masquerade field.

That should do it.

Only 1 choice actually.. you don't want to change the computer's hostname if it's a member of a domain.  I presume AD is configured to use fc2h.com as it's Domain Name?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Only change the IIS masquerade...
So follow my original answer because it still applies...

Thx

I have also made the changes below

inorder to receive emils for certain domain that smtp address must be added in ur
recipient policy for example if u want to recieve emails for ABC.com that address
must be in ur recipient policy orelse ur exchange will refuse those emails destined
for ABC.com(one function of recipient policy is to tell exchange to handle or accept
emails desyined for that domain).
U must also keep in mind that ABC domain must be registered and ur isp must
create an MX record A record and a PTR record pointing to ur public ip address.

I did not see SMTP configuration in IIS.
