Have you done any other SMTP testing? You can go to MXToolBox.Com and do an SMTP test. First go to the site, plug-in the domain with the issue and click "MX Lookup". Once the results come back click on 'SMTP Test' and let us know the results. Or Go here - https://www.testexchangeconnectivity.com/ - and use the 'Internet Email Test' section for your testing. Let us know your results.JAUCG

Here is what I would do: Check your MX record to make sure that both domains are going to the correct destination.Check the email address that you are sending to externally is correct and that it is valid on the user object in Exchange.If you are using an external SPAM blocker, check to make sure it is not getting blocked there or that the domain/email address is defined.Check to see if the mailbox can accept external emails.Restart the Exchange Transport service and try again.Check to see if the SMTP service is installed as well. JAUCG

Every thing seems to be setup correctly let me brief you I have got one local domain ABC.local I have created new user under the same domain Created new accepted domain for xyz.com & recipient policy Under abc domain local user have created smtp address for tech@xyz.com Have created MX record for xyz.com for abc domain hostings at GODADDY Also created one MX record for abc where XYZ is hosting plesk panel. Not sure i f iam skipping with any step also checked with recyling transport services but issue still persist.. do you have your direct contact details so that I brief you & further elaborate via TEAM VIEWER . Thx

Also have cross verified the XYZ domain is added in BARACUDA domain list

hi, >>>Have configured & created recipient policy & accepted domain as per KBhttp://blogs.technet.com/b/sbs/archive/2011/04/13/how-to-configure-sbs-2011-standard-to-accept-e-mail-for-multiple-authoritative-domains.aspx for my second sister hosting company. One exchange two domain, is it right? What's your mail flow? I think we should get more information about your exchange environment. If you only have one exchange server. You only should do three steps that you can use the new domain to receive mail. 1. create a new accepted domain 2. new a address policy then assign to users 3. create a new mx record for the new domain. Accroding to the test result, it seems message has been routed to your exchange server. MX record i can ensure it is ok. If you use message tracking log to search the message which is sent to your new domain user, can you find some more information? hope can help you thanks, CastinLu TechNet Community Support

Yes in current setup structure i have got One exchange with two domains Domain1 ABC.com is internaly & externaly hosted , Domain 2 XYZ is only hosted external no internal DNS server. My exchange Mail flow i have got one CAS & MAILBOX on seprate server & got Baracuda for SMTP antispam & AV I have checked with creating a new accepted domain Also created new a address policy & assign to users Have created a new mx record @ ABC external hostings GODADDY like mail.xyz.com priority 10. Checked with message tracking log to search the message which is sent to my new domain user, i cant find anything its getting blank with no result? Please suggest if i need to check exchange rules or something or tell me your personal email where ican contact you in detail . THX

any suggestions will be more than welcome

I suggest that you delete your duplicate posts above.Martina Miskovic

any suggestions will be more than welcome Do you even have mailboxes with the new accepted domain? The error #Mailbox unavailable" tells us that you dont. What's the result if you test the mailflow? Example: Test-Mailflow EXCHANGESERVER -TargetEmailAddress someuser@xyz.com Martina Miskovic

Thanks Martina for the post .. please find the below reults [PS] C:\Windows\system32>Test-Mailflow EX02.abc.local -TargetEmailAddress test@xyz.com RunspaceId : 3ce426f5-46f0-457b-96e9-89f2afcbc06e TestMailflowResult : Success MessageLatencyTime : 00:00:01.0326358 IsRemoteTest : True Identity : IsValid : True do i need to double check my recieve connectors ? or barcuda rules ? not sure

Additionaly I am just controlling NEW DOMAIN XYZ mailboxes via email address policy on specific OU of XYZ user in ADS Whenever i tries to create new user it gives me abc.local from the drop down menu of domain selction for new user setup in exchange. Once i create the user i just change the alias in email policy from test@abc.com to text@xyz.com Not sure if i am doing it rightly timely assitance will be appreciated . Thanks

Do i need to edit default email address policy as well ? Since i have just created new email policy to apply on specifix XYZ OU

hi, If you can disable your barcuda, i recommend that you do it and try again. I guess may be the issue is caused by your barcuda. >>>Do i need to edit default email address policy as well ? No, i don't think so. hope can help you thanks,CastinLu TechNet Community Support

checked but same issues persist i need to keep my CUDA alive with second domain hosting pls suggest

If you have a Barracuda, you should be able to look at the logs for the domains to see if the email is being dropped, queued or whatever. That way you can eliminate that from the list.JAUCG

hi, When adding another domain name to your exchange you need to do the following:- 1. Add the new domain to your exchange hub "Accepted domains" e.g test1.com is the default domain and the new test2.com domain. Also create an A record which points to the same external IP address, e.g mail.test1.com to 1.1.1.1. and mail.test2.com to 1.1.1.1. 2. Create a new OU for the domain on the domainC/mail server (without the .com, etc..), this will keep things tidy. 3. Create your new test user as usual (eg. test@test.local), just select default domain name (*@test.local) * It is OK, this will not show up as your default domain when sending emails. we will change this after you create the user. 4. Create the new mailbox in Exchange with the new user (test) and select the default domain (test1.local). If the user already exists then just change the login name to test2 but keep the name the same e.g first name "test" but the login will be different. 5. Once the user is created, go to the properties of the user and select "Email Addresses" and then un-select "Automatically update email address..." 6. Now you will be able to add the new email address you need to assign to the new user with new domain name:- a) Select "Add" and create the new email address, e.g test@test2.com b) Now select the default email address which you created by default (e.g. test@test1.local) and delete. 7. Your done, but i would test it by sending the emails to AOL.com to make sure!!! In some cases you will have to ask your ISP to setup a rDNS. but in my past experience if AOL.com except your emails then everyone else does and i have done this without asking my ISP when adding the second domain name. Never failed before.... Hope this helps.

Have followed all steps except an A record addition here with similar pub ip of default 1st domain.

hi, Sorry, i can't find the A record of mail.test2.com. You should have and the ip should be 12.19.15.42 Then exchange can use these two records to connect to your exchange server and send/receive messages. hope can help you thanks,CastinLu TechNet Community Support

Hi, The error which you have posted here, it shows 550 550 5.1.1, -Currently it says rejected by the recipient domain, where i have seen this error we usually get when the recipient is not in the Org. as i see many response on this Topic - this sounds like you are good with the configuration on the exchange part. Now we need to look at few things. 1. DNS Do you see any difference - while email going thru outbound & coming to inbound, how the DNS is structured. 2. Email Gateway (Baracuda) Do you see any Certain 3. Mail Flow test -establish the session using telnet from outside to your SMTP gateway and send email using command line with the old domain Then same try with xyz, new domain. -create one user with both the smtp address (older domain & new Domain) then try to send email from public account on both the id, see the header, what difference do you see there. I am sure there is somthing in Baracuda which is causing issues. But just try these, you might get some clue on this. Regards, Ashwini Know more about Messaging :-)

Appreciate your feedback here , i believe the issue you have highlighted seems to be the one with the posted & current issue we are currently facing with. Attach are the SMTP test reuslts for the hosted public domain names seprately.

At this point this is something, which is stopping you on the Email Gateway which is you Barracuda. The good idea would be to check on the Vendors (Barracuda) forum, Check what they have to say on this. I don't think you have anything missing from exchange side. All the best further!
