SMTP Relay Server and Mail Aliases

I have front-end and back-end Exchange.
I do not want that my front-end Exchange has SMTP relay functionality.
I want to deploy a SMTP relay server in DMZ.

My problem is:
This SMTP relay server is not a member of my Exchnage AD domain and does not 
know about mail aliases in my Exchange domain. I do not want that I open 
additional ports on firewall which is between my Exchange domain and SMTP 
mail relay.

My question is:
How can I inform that SMTP relay server knows about all mail aliases on my 
Exchange domain? 

Best Regards

Export the SMTP addresses from the AD and import them into the SMTP
relay server's database(s).

Knowing what software you plan to use would be a big help. Postfix,
sendmail, qmail, exim, something else?

Continual Cannot Connect to Server errors
Outlook 2000 works fine for anywhere from 30 minutes to 2 hours, then suddenly stops connecting to the server. Closing and reopening Outlook solves the problem. I've done KB820672 and the problem isn't with the server - this actually happens with two different servers/mail accounts. Both accounts work perfectly in OE6.0 (which I also use and have open at the same time, although I don't have the same account on both). I have all the critical updates for Office, WinME, IE, etc. Thanks, ...

SMTP restrictions #2
A few questions: If I configure the "Limit Message Size(KB)" does this pertain to the attachments as well? Also, does it affect both inbound and outbound? If the "Limit Message Size" is exceeded by the attachment does the attachment get stripped and the message (body) go through? If nothing goes through, does the sender recieve an error? Sorry so many questions. Thanks! Message size is the sum of the headers, body and the attachment. There is no setting specifically for the attachment size. When there is a violation, the entire message is bounced back to the send...

OUTLOOK 2003 with or without exchange server
I recently have begun upgrading a small office from Outlook 97 with Exchange Server 5.5 to Outlook 2003. I have some questions about this. In this office everyone needs to be able to access everyone elses calendars (6 in all) . With outlook 97, you were unable to do so without using exchange server. Now, with Outlook 2003, will they be able to access each others calendar without using any exchange server? If they need exchange server, will they be able to remain with exchange server 5.5 or will they need to upgrade to Exchange Server 2003? Any help would be greatly appreciated. &g...

Mail Message being delivered every two hours
Hi, We're currently running exchange 5.5 Sp4 and are having the following problem. A user sent a message to a group of user yesterday afternoon, and ever since then, everyone in the group has been receiving the message in exactly two hour intervals since the message was sent. Can anyone advise on how I can resolve this problem. Thanks SteveO: The problem could be that the sender's Outlook OST (offline file) is corrupt. If that's the case, then do either of these: a) On the user's PC, open up the mailbox in OFFLINE mode. You should see the message in the Outbox - de...

Mail merge #8
I have created a 19.2 mb 8 page newsletter. I want Kinkos to print it so that each newsletter copy is printed with an addressee on the front page. That means I have to do a mail merge. When I select "print to Kinkos file prep tool" it takes about 1 minute per copy and I have 300 addressees to mail to. That means 5 hours and probably will run out of memory or so says Kinkos pro. Kinkos says that I can also just take the mail list which is an MDB file and send it to them as a PDF file which I don't think can be done. Anyone out there who has been through this?

The server is patched with all the MS patches - except the "sp4 rollup 1", When we go to restart the server - it seems to hang - there are no entries in the event log - only the visual of the " admin.exe" program failing to shutdown.
