hard direct fail and no available shadow servers

I was going through message tracking, external user may not be receiving emails from us, and I ran into these two errors I had not seen before, Hard Direct Fail and No Suitable Shadow Servers.

the email in question is being forwarded from an AS400 through our Exchange 2013 through a relay connector, also we have two Exchange 2013 servers and a witness server to form a DAG group.

does the shadow server refer to the 2nd exchange in the DAG group?

I ran several status checks on the DAG group, and status appears to be ok.

Hi, 
We are receiving this bounce back from this one particular external domain. 

smtp;550 No RDNS entry for 175.a.x.141

our mx : mail.x.shm.com = 175.a.x.140

our ptr : 175.a.x.140 = mail.x.shm.com 

175.a.x.141 is our WAN 1 interface of the firewall.

Why does the external domain reject the RDNS.

Out of Office (Barracuda with Exchange 2013)

Hi,

We are using Barracuda Spam Firewall 300Vx with Exchange 2013 (Tenant) and disable the features Allow Empty Inbound Senders Domain/Allow Empty Oubound Senders Domain. Please review the first image.

I configure OOO on my company account like shoaib@domain.com and send a test email from Yahoo/Google/Hotmail and other domains to company account. I received the email but OOO reply blocked on BC as from sender is empty. Please review the second image.

I discuss this issue with BC support, They said that below issue is related to your exchange server as FROM address should not empty. Someone please let me know how to resolve this issue as we enable the SRV record on DNS and auto configuration is working fine. 

We configure Send Connector on Exchange Server and all Inbound/Outbound emails are passes through barracuda spam firewall.

Allow external out of office message only also enable on Remote Domains.

Hi,

I have had my Exchange up working for a while now.
Recently my boss asked me to create a e-mail account with a different domain name.
Everything worked fine with inbound sending and receiving, outbound sending works fine aswell.

But we noticed that the new accepted domain do not receive any outbound mail.
Can anyone give me a hint on where I should start troubleshooting?

Thanks!

Emails inbound from some domains are failing

Have Exchange 2010 running on a VmWare virtual server.  Generally the mail is flowing however with SOME domains (maybe 3 at the most) the Sender is getting the following message when they try to send an email to our domain. 

One more note:  We have no problem internally sending an email to the external domains in question.  The only issue is when the external domain try to send emails to our domain. 

From: Microsoft Outlook

Sent: Friday, February 19, 2016 1:45 PM
To: XXXXXX
Subject: Delivery delayed:testing

Delivery is delayed to these recipients or groups:

"from external to internal"

Subject: testing

This message hasn't been delivered yet. Delivery will continue to be attempted.

The server will keep trying to deliver this message for the next 1 days, 19 hours and 55 minutes. You'll be notified if the message can't be delivered by that time.

I have done the following to try and troubleshoot:

1. Check packet monitor on firewall

2. Created exemptions for troubled domains on both firewall and Content filter

I could use some help on this issue. 

Thanks in advance.

This is the error I am getting and I did email to delist@messaging.microsoft.com and I am wondering when will my IP get unblocked as this is causing a lot of communication issues. I checked my ip for blacklist but its not in any database. Hope I'll be able to find some solution soon on this.

Mailbox & Send Connectors

Hey all,

So I am trying to see if it is possible to not allow users on one mailbox database be able to send externally. I have two databases, and was hoping to stop users on one of the databases from sending external to the organization. I have yet to find anything on it in my research, so I was hoping someone would be able to point me in the right direction.

Thank you in advance!

Hi There

We're running on an Exchange 2013 server. When users get a NDR (look OK at this time), but when forwarding the NDR to system admin, they get garbled into Chinese (or what looks like Chinese). Any ideas on solving this ?

Delayed Messages

We recently installed Exchange 2013 Enterprise Server to upgrade Exchange 2010 Server. After installing and configuring new Exchange I migrate a few users as a test (internal DNS and NAT still points to the old server). I was able successfully send e-mails back and forth between servers without much of a delay. Then I changed internal DNS as well as firewall settings  to point the Exchange 2013 server. Users on Exchange 2013 server are still able to receive e-mail without delays but when they reply, it takes about 20 minutes for the messages to be received by the users still on Exchange 2010. Same problem from external users as well.

I checked all the setting and I can't find any issues. Does anyone have any ideas what might be going on?

Thank you,

Serge

DNS conditional forwarder messed up mail flow between forest domains - Split DNS in use

February 12, 2016, 12:54 pm

I have what might be a simple problem but i'm not sure.  We have two AD domains in separate forests. Both have separate Exchange 2013 deployments.

One is for a company we are taking over and I eventually need to set up a one way Trust from their domain to mine, both AD 2012. A prerequisite for setting up a trust is that you set up DNS conditional forwarders on both sides for each others domains.

At their domain, they only use AD DNS.  On our domain we use SPLIT DNS.  That is, we have an external provider that announces authoritative DNS for use publicly so that for our externally facing websites and services, they get a lookup or a routable IP that hits our Firewall and is translated to a NAT IP internally.

For internal DNS though, we make similar records, but not to the routable IP but rather the internal unroutable IP, like 192.168.*.*

So for mail routing on the internet, we use external DNS MX record that routes to our virus/spam firewall external IP.  This other company sends us mail and gets it to us just like any other external entity.

We set up a site to site VPN so we can route to each others unroutable space.  Ours is 192.168.25.* theirs is 10.0.0.*

When I set up the conditional forwarder for our domain, that forces their DNS queries to go directly to our AD DNS server at the 192.168.25.2 address and not the external DNS provider.  This setup worked, and I could ping internal non-externally advertised internal host names after I set it up.

However, email flow broke. They started getting the following bounce message.

Delivery is delayed to these recipients or groups: 

Generating server: EMAIL2.NTDOMAIN.local
Receiving server: mydomain.com (192.168.25.2)<o:p></o:p>

Remote Server at mydomain.com (192.168.25.2) returned '400 4.4.7 Message delayed'
2/12/2016 2:54:49 AM - Remote Server at mydomain.com (192.168.25.2) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect. Winsock error code: 10061, Win32 error code: 10061." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was 192.168.25.2:25'<o:p></o:p>

So basically delivery is attempted to my domain controller and not my exchange server.  I assume that when I set up the forwarder it would use my MX records in my domain.  I checked and I do have several MX records, some for Sharepoint servers, but the one with the lowest priority (10) was my Exchange 2013 MB server.  So i'm not sure why mail delivery was attempted to my domain controller.

Any help is greatly appreciated.

Distribution Group Sender Restrictions Not Working

I've created a new distribution list via the ECP and added myself to it.  In the list's details, under delivery management, I have 'Only senders inside my organization' ticked. However, when I send an email from an external gmail address, it goes through.  What am I doing wrong?

Limit message size for a specific distribution group

February 24, 2016, 10:03 pm
$

We have a dynamic distribution group than includes all users in our organization (about a thousand mailboxes, and this number is going to grow significantly in the next few weeks). Only specific senders within our organization are allowed to send messages to this list. Unfortunately, some of them have no understanding of even the most basic concepts of working with files and pictures, which results in sending multimegabyte messages to that list (mostly scanned documents). In turn, it results in huge database growth every time such messages are sent, which consumes limited space on Exchange server and backup system volumes. It's no use do explain the culprits how it should be done properly, and I can't forbid them to send messages to this list at all. So the only way to solve this problem is to implement technical restrictive measures.

However, standard methods don't work here. There are no message restrictions for distribution lists, and I can't even create a transport rule as Exchange doesn't accept a distribution list address in the SentTo field. In addition, I don't want to restrict the sending message size for those users as sometimes they need to send valid big-sized messages to other recipients.

Any ideas what other ways of control I can implement?

migration Lotus Notes to Exchange, how to migrate confidential emails (in LN encrypted)

December 5, 2014, 1:50 am

Hi,

we're investigating a migration of Lotus Notes to Exchange. One issue is the migration of encrypted mail. How to keep them confidential in Exchange?

We have users like a secretary that has read/write access to a mailbox of a manager. If another user mails the manager with confidential information, he encrypts it in LN before sending it, so only the mailbox owner can open the message. Is this possible in Exchange 2013 and in Exchange online? Heard that you can set things via IRM, but that with Outlook web access the secretary can set the manager's mailbox as primary and than will be able to open the confidential email....

best regards,

Hans

Unable to receive mail in Exchange 2013/OWA

Hi all.

I'm fairly new to Exchange Server, so do forgive me if this is an extremely stupid/simple question.

I've set up a copy of Exchange 2013 on Windows Server 2012 R2 Datacenter (a clean install, may I add) I am able to send messages externally from OWA, but am unable to receive any responses.

I have run the Connectivity Tester in the Exchange Toolbox, which reports the following error on Inbound SMTP

The server returned status code 451 - Error in processing. The server response was: 4.7.0 Temporary server error. Please try again later. PRX2
Exception details:
Message: Error in processing. The server response was: 4.7.0 Temporary server error. Please try again later. PRX2
Type: System.Net.Mail.SmtpException
Stack trace:
 at System.Net.Mail.DataStopCommand.CheckResponse(SmtpStatusCode statusCode, String serverResponse)
 at System.Net.Mail.DataStopCommand.Send(SmtpConnection conn)
 at System.Net.Mail.SmtpClient.Send(MailMessage message)
 at Microsoft.Exchange.Tools.ExRca.Tests.SmtpMessageTest.PerformTestReally()


Elapsed Time: 2164 ms.

The other issue I'm having with Exchange is that outgoing email is VERY slow to leave the drafts folder (can take upwards of 10 minutes sometimes for a simple "test" email).

What am I doing wrong? Do I need to open up any ports in the firewall? I've tried opening the standard mail ports before now, but nothing changed.

Thanks in advance;

Toby
