Can Exchange server send a local email address to a different smtp server?

[Brazen]

I need a couple email addresses to be handled by a different server. All our email addresses end with @company.com. Can I have a certain address, such as xyz@company.com, be sent to a different smtp server?

Yes, use SMTP connectors.

I suppose I have to create a contact or something first in Active Directory? Or will it work even if no user or contact or any sort of mailbox exists in Active Directory for the address I want to relay?

Ok, on the General tab for creating an smtp connector, I give it a name, choose to relay all through the smarthost and enter the name of the smtp server I want the emails sent to, and select the Exchange Server as the bridgehead (not really sure what the bridgehead is). I then go to the Address Space but it won't let me enter a single email address. It looks like I have to enter the domain (company.com). Then how do I tell it which email address in that domain should be sent to the smarthost?

Do I do it on the Access Resctrictions tab? Do I just set it to deny by default and enter the specific email addresses I want allowed on that tab to have them relayed through this connector?

If both domains are handled inside of the same Exchange Org. (say just 2 servers in the same org. and you've logically broken them apart by domain) than there wouldnt be a need for an SMTP connector; your first exchange server would see that the mailbox exists on the domain and (assuming it has connectivity) pass it over to the other Exchange server.

If these are differant Exchange orgs or the second server is not Exchange use a SMTP connector to send all email for that domain across and be done with it. It's up to the recieving server to determine whether those addresses are valid in its namespace.

If you have a mail relay server, it can do the parsing for you.

if not, get one or create new connectors.

I prefer the relay way myself...

We have a relay server - it's for spam and virus filtering, actually - but I don't believe it has the ability to send specific addresses from the domain to a different smtp server than the rest of the domain addresses. I found information on smtp connectors, and it looks like they will do that, and they set up just the way I expected. I have yet to test it though. And, by the way, the other smtp server is not an Exchange Server, it is a Sendmail server.

What product are you using for your mail gateway? I run ClearSwift's MIMESweeper for SMTP and it gives me the ability to forward mail destined for differant domains to differant hosts.

hmm, I do not know if this can be done -- forwarding a single account box to an alternate mail server, without the use of additional sub domains? If you can use an alternate sub domain, then that will work for sure, even if that subdomain delivers to the same actual account (optional).

v
joe.user@somedomain.com (external mail relay)
---> forward to joe.user@somedomain.com (internal mail server)
---> forward to joe.user@test-for-hot-pron.somedomain.com (alternate mail server)

If you don't use an alternate domain, it will never see another server, thanks to DNS -- the MX records for your domain say what they say, and that is it -- if they point to your box, it's going to your box ... unless you are hardcoding things, in which case you're already down a dark path.

Just my $.02

It looks like SMTP Connectors solved this problem. I had to create Contacts for each of the addresses, and then tell the connector to only pass those Contacts and use the other server as a Smarthost.
