Error "550 5.1.1 ADR.RecipNotFound" for existing user

April 17, 2015, 4:35 am

Hello!

Our Exchange infrastructure description, briefly:

1. Using Exchange 2013 CU7

2. 2 x MBX+CAS servers (EX1, EX2)

3. 2 x Edge servers (mx1, mx2)

4. DAG, 4 DBs

5. Hybrid Configuration: 200 local users, 15 cloud users

Our case: sometimes our users receive NDR while sending messages to existing mailboxes:

"Remote Server returned '550 5.1.1 RESOLVER.ADR.RecipNotFound; not found'

For example, user sent 2 messages, first caused NDR, second was successfully delivered:

Reverse DNS does not match SMTP Banner

I am having issues with some company's not being able to send emails to staff on our exchange server because it fails a Ehlo test. the users sending the email get the following message.

<User@renfrewhosp.com>:
host exchange.renfrewhosp.com[142.46.224.120] said:
554 5.7.1 This message has been blocked because the HELO/EHLO
domain is invalid. (in reply to MAIL FROM command)  now our Exchange servers domain is not the same as our email address domain. I have set the FQDN on the send connector to renfrewhosp.com but when I go to change the receive connector I get the following error

error

If the AuthMechanism attribute on a Receive connector contains the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values: the FQDN of the transport server "EXCH01.rvh-win2k3.com", the NetBIOS name of the transport server "EXCH01", or $null.

any help would be appreciated. I'm running exchange 2013 cu6 on server 2012.

Hi

We just set up a new server 2012 standard r2 with exchange 2013, all brand new install and we can telnet to port 25 internally, but not externally.  We have connected the server to 2 different firewalls and experience the same issue so it does not appear to be a firewall issue.  Setting up smtp on port 26 appears to work, however port 25 is being blocked for some reason.  The windows  firewall is disabled.

any ideas would be appreciated.

Hello everyone,

I have zen.spamhaus.org setup on the edge server and it seems to be blocking a lot of spams. However, some emails is still passing through the blaklist even though on the test-ipblocklistprovider show that the IP is on the blacklist.

Please, see the email below that was supposed to be blocked but it was not:

Exchange 2010 with ip block list providers using custom error message and Get-Agentlog Exchange Shell cmdlet conflict.

April 6, 2015, 3:56 pm
$
0
0

When ip block list providers are configured the standard error message for rejected messages in the Agentlog log field 'SmtpResponse' contains '550 5.7.1' at the beginning of the message.

When ip block list providers are configured the custom error message for rejected messages in the Agentlog log field 'SmtpResponse' contains '550-5.7.1' at the beginning of the message.

The Get-Agentlog powershell cmdlet in the Powershell Exchange Management Shell throws an exception on the customized log records as below and the record is skipped by the Get-Agent cmdlet.

The SMTP response at line 213 in file "C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\AgentLog\AgentLog20150406-1.LOG" isn't formatted according to RFC 2821.
Parameter name: smtpResponse
    + CategoryInfo          : InvalidArgument: (:) [Get-AgentLog], ArgumentException
    + FullyQualifiedErrorId : 78B82C6B,Microsoft.Exchange.Management.AgentLog.GetAgentLog

This behavior prevents the use of the Exchange Management Shell Get-Agentlog cmdlet in the processing of the Exchange Agentlog files. Is this behavior by design? I would like to use both custom error messages and the Get_Agentlog cmdlet.

Thanks in advance.

Internal Relay Mail being Received Twice

April 20, 2015, 11:34 am
$

We are using our Exchange 2013 SMTP receive connector to relay mail from our fax server to internal users.  Several times a day, our users will receive duplicate or triplicate emails from this service.  Looking at wireshark captures and the SMTP Receive logs, it appears the RightFax successfully sends the data (including the "." at the end) but doesn't receive a " 2.6.0 Mail queued for delivery" message from the Exchange server. It then resets the connection to send the message again. Often, it will receive a successful "mail queued" message the second time, but if not it retries and receives the "mail queued" message the third time.  However, on the recipient end, they receive two/three emails, all with different conversation ID's. 

If we switch the email gateway in the fax application back to our legacy Exchange 2007 environment (which we have not yet decommissioned due to this issue), the issue goes away completely.

So far, the fax application is the only application with email being relayed that we have received complaints about duplicate emails. 

We have tried:
-  Changing the application to point to a different 2013 server that doesn't have as much internal relay traffic
-  Increasing the MaxInboundConnectionsPerSource to 100 and MaxInboundConnectionPercentagePerSource to 100%
-  Increasing the timeout on the application (up to 6 minutes)

Have there been any changes to SMTP response in Exchange 2013 that would cause these issues?

Hello, dear Fellows,

We use an Exchange2013serverto relaytwoweb applicationsvia a Front-End Transport Receive Connector, properly configured.
All messages sent by the ASP Web Application, are receivedby all the recipient domains.
But somes messages sent by the PHP Web Application are not receivedby some Domains, remaining within the queue, with error messages:
554 5.4.4 SMTP.SEND.DNS.NonExistentDomain;non existent domain
451 4.4.0 Primary Target IP responded with 421 4.7.0 "ServerName" Too many errors "Cannot achieve “Exchange Server authentication”.” Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts…"

Do you think this is a PHP problem, or an Exchange problem ?
Thanks for your answers

Hi All,

I had enabled Pipeline Tracing on both my Mailbox 2013 (DAG).

Noticed some times the message log in the pipeline trace folder doesn't show all 3 EML files in it.

Under what circumstance Original.EML is not logged, but Routing.EML / SMTP.EML is logged, or vice versa?

Hope someone can help me on this.

Thanks and Regards,

Redirect Rule - Delivery has failed to these recipients or groups

First of all my apology if this is wrong Forum. Please guide me to correct forum.

Scenario is that we need to send emails to AD Group using C# code or script.

First we tried C# code and it don't work, as per our finds, log in / password is required. Also, it was taking to much time because of protocol  and we need to send 10 to 15 emails at same time.

We tried script and this time we created a mail box say, temp. We send emails to temp and added rules on bases of subjects of emails.

Now, issue is if we setup forward rule, temp is able to forward email to AD group. If we setup redirect rule, email is not send to AD Group and temp received failure delivery.

Delivery has failed to these recipients or groups:
AD Group Name
Your message can't be delivered because delivery to this address is restricted.
For more information about this issue see DSN code 5.7.1 in Exchange Online.

 We even made temp owner of AD group.

Any help?

Hello,

When I received a message from the external, I have a "loop" in my mail flow. I have not a problem with the receiving but it is strange.

My headers are the follow :

Received: from exchsrv.domain.com (192.168.1.x) by exchsrv.domain.com
 (192.168.1.x) with Microsoft SMTP Server (TLS) id 15.0.1044.25 via Mailbox
 Transport; Fri, 24 Apr 2015 13:05:07 +0200
Received: from exchsrv.domain.com (192.168.1.x) by EXCHSRV.domain.com
 (192.168.1.x) with Microsoft SMTP Server (TLS) id 15.0.1044.25; Fri, 24 Apr
 2015 13:05:07 +0200

 Microsoft SMTP Server id 15.0.1044.25 via Frontend Transport; Fri, 24 Apr

Note the uppercase in the second receive.

I do not really understand when the problem could be.

No Internet Mail Group Exchange 2013

Hello, 

I'm trying to restrict a group of users outside mail access and only allow internal mail communication within our organization. In the management console for Exchange 2007 and 2010 it was pretty straight forward creating transport rules. How ever through the Exchange Admin Center in Exchange 2013 I seem to be having more difficulty. 

I logged into EAC, from recipients, i went to the groups page and created a new security group, and then went into its properties. Under properties I click on delivery management and have "Only senders inside my organization" selected. I was under the impression this would stop email from the outside coming in, but I was incorrect because I can still send mail from my gmail or yahoo account to useres I put in this group.

Stop users from sending outside email, I haven't even attempted since conditions and actions in the transport rules seems to have changed and I can't seem to find the correct action to do what I want.

Anyone have success doing the above with outlook 2013 and EAC? I'm not opposed to doing this via powershell either if needed. 

Thank you!
