Default Forwarding email to Blackberry to a remote server

Please Login to Remove!

I have Blackberry with an email address on a server in NYC that runs BES 4 and exchange 2000. And I want to have people email to an address on an exchange 2000 server in Albany, NY and have exchange forward the emails to the person's mailbox and to the Blackberry in NYC. I have setup the forwarding system as prescribed by MS, but when people on the NYC domain email the Albany address they get this error message:

From: System Administrator

Sent: Friday, February 11, 2005 1:57 PM

To: Gary

Subject: Undeliverable:RE: Delivery Status Notification (Failure)

Your message did not reach some or all of the intended recipients.

Subject: RE:

Sent: 2/11/2005 1:57 PM

The following recipient(s) could not be reached:

Gary on 2/11/2005 1:57 PM

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.

<mail.serverinalbany.com #5.5.0 smtp;551 This is not a relay host - mail must be to or from host domain.>

It works fine for everybody outside the NYC domain. On the Albany server I setup a connector, added the NYC address to allow relay, and set the server to allow automatic forward. What am I missing?

Is "Gary" the name in exchange, or are you substituting gary as an actual email addy? I mean, are you actually entering "Gary" or "Gary@emailserver.com"?

Does this work from desktop clients?

it's his name.

Desktop clients? If you mean from the computers in the domain in NYC then it's no as I previously stated.

Default Just add a rule

Why not just add a rule to the mailbox that you are sending to that tells it to forward all incoming messages to the BlackBerry enabled mailbox?

do these two exchange servers house the same domain, just different physical locales (are they in the same org)? from your wording, it appears that you have control over both exchange servers, but it doesn't appear they share the same domain name.

usually this error comes up when you are sending FROM a domain TO the same domain but not WITHIN that same domain. we had this issue with a CRM (salesforce) sending back to our users (with the FROM domain as our own). obviously it would see it as a relay.

anyhow, it just seems like there are some permissions you might be overlooking. again, i'm not sure what all you have access to and not and what domains are which, etc etc. try listing out a bit more details...

You are pretty much correct. The Albany and the NYC domains are different names and they are not linked, but they are part of the same organization. I setup a second account on the Exchange server in Albany with the email address of the account in NYC (BES) and forwards email to that NYC account. Then I set the main account in Albany to forward to email to the second account on the Albany server. Works for everybody except for the people physically on the NYC domain.

On either domain are the users names duplicated or do the users have an additional smtp address that resides on that other domain? Also do both know about the others dns servers? It kinda sounds like you may be zone hosting each domain in the others dns? If you are using w2k3 you can do conditional forwarding in dns. Meaning you can put in an entry that says any request for a lookup on theotherdomain.com should forward that request to 1.1.1.1 DNS server, 1.1.1.1 would be the other domains DNS server.

Just sounds like something is confused due to either settings in AD for the users or due to some odd DNS.

Zone hosting meaning that I created a zone name for the other domain on the DNS server? I am using Windows 2000 Server. I don't have the other domain on the DNS server. Would it be a good idea to create it's own zone name?

Well, regardless of whether this is your problem or not you probably want to have your internal dns represented in some way, I bet something is getting a bit confused, now it may still be functioning, I can't be sure of course.

If you know this lay it out for me.

So you have DNS servers in both domains of course because you have domain controllers using Active DNS.

Now, what DNS servers do you have set as the forwarders from each of those DNS servers. Meaning, if someone does www.yahoo.com, your domain controllers don't host that zone of course, so you forward the request out to other DNS servers, normally root servers or your ISPs DNS servers.

Now I would not bet that the DNS is your current problem from what you just told me, I would take a very close look at the users in Active Directory, see if they have any email aliases that you think may conflict, see if on the other domain those users exist for some reason, or users with the same names etc.

You see where I'm going with this? Active Directory can be amazing when it works properly but can be an absolute nightmare with the most minor of mistakes.

So check AD. Also go to an outside source like www.dnsstuff.com and get the full records of what the world sees, then compare this to what you see from boths sides with an nslookup to get all of the A records and MX records.

Note which DNS server the exchange box and exchange connector boxes are using as well.

Sorry I havn't narrowed it much but I bet somewhere above is the path to your issue.

Both servers are behind a firewall and have internal IP address. All the data is forwarded by the firewall.

I know all the emails are correct because everybody is receiving email. The forwarding account (Albany) has the email address in NYC in the email section in the general tab and the Email Addresses tab.

Ok I can see that being a problem just not 100% sure what combo would work. Let's think through this.

[email address] forwards to [email address]
[email address] has an email alias of [email address] as an email alias, ok right there is a problem and I'm trying to work through it in my head to explain it.

My inital thought is that the albany forwarding account should not have the nyc.com alias assigned to it. That would likely do some odd confusion, however it's late and I can't seem to get it 100% figured.

You should just have the [email address] addy forward to the [email address] addy. There is no need to have the [email address] smtp alias in the [email address] active directory account.

If I am confused try to clear it up for me and we can probably get you further along.

loonews, i think you are correct.

francescos, just set up a contact for the nyc.com email addresses and have the albany.com email forward to it. your issue is stemming from putting a non-hosted domain as the primary smtp on another.

i am getting the same idea that loonews has for your setup.

basically, if you have a non-trusted (and i know you said you set this up, which leads me to believe you set it up wrong) host sending emails to a domain while having the sender as that same domain, then it will get bounced due to open relay security.

basically, if you have a nyc.com email address hosted on the albany.com mail server, and albany.com's IP address/server is not trusted by nyc.com, then sending to nyc.com from nyc.com (although its really from albany.com) will be bounced with the same error you have above.

how's that for confusing..

i'm not sure how microsoft has implemented trusts, so i can't really help out on that front. with surfcontrol (our front-end), we simply have to add the IP address of the mail server we want to trust and then specify the type of trust (open, send/receive, etc).

Well here is the other issue. I can't get rid of the email address from those two property tabs. If I delete the exchange mailbox and then recreate it exchange will put the email address back into those two properties.

So, I guess the next step is to create some kind of trust between the two servers? Does the SMTP connector thing have to be on both servers?

what version of Exchange are you using? if 2000 (and possibly 2003), open Exchange System Manager, go to Administrative Groups, go to your group, open up the mail server, then Protocols then SMTP. right-click on Default SMTP Virtual Server and click on Properties. click on the Access tab then click on the Relay button.

you should only have to do this on the NYC server, adding the IP address of the Albany server. you mentioned both are internal networks, but i'm not sure how routing is setup. if routing is setup between both networks so that they talk to each other internally (i.e-the mail servers would see internal IP addresses and not an external firewall IP), then add the internal IP address (be specific, as this does open up a potential security flaw). if they see the firewall IP address, then add the external IP address. after you add it, right-click on Default SMTP Virtual Server and click on Stop (then Start after its stopped).

see if that works.

I don't really understand why you wouldn't be able to remove those, are you a domain administrator? I'm not arguing but you really should be able to pull up the address aliases and remove any or all on any account, should not have to rebuild the account.

I'm sorry I guess I've never been in that position or know how your AD is setup, but I add and remove email aliases daily from accounts so can't be sure I understand that one.

You are on the right track, just have to find the end way to get there

as loonews mentioned, it makes no sense why you can't do it an easier way than setting up server trusts.

why not just delete the nyc.com mailbox/account and readd it back as a contact then setup forwarding on the albany.com's mailbox to the nyc.com contact.
