Emails destined for Outlook.com rejected with 4.4.7 - theory?

March 18, 2014, 8:22 pm
$

0

I have a client that is a Law Firm. They are trying to send emails to a company that uses Outlook.com as the host for their emails. Whenever my client sends an email to the company, the messages sit in the outgoing queue of their server with the error 4.7.7.

When tested from my own exchange server emails are delivered to their server. (delivery receipt received)

When I check the hosted domain via MXToolbox, it reports all is ok

My question.

Does a customer who has email hosted on Outllook.com have any ability to block a sender (either in a spam filter or junk mail filter) that would cause this to happen and generate the 4.7.7 error.

I am wondering of the company is actually doing something to block my Clients email domain from being accepted in some way.

SMTP DNS errors in Mailbox Transport Service

Users have reported that intermittently, inbound email is being returned to sender with an invalid domain name: #554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##

I'm seeing DNS lookup errors in both our TransportRoles > Logs > Mailbox > Connectivity > Delivery and Submission folders.

In Delivery:

2014-03-12T19:24:53.739Z,08D102BA4526E381,SMTP,mailboxtransportsubmissioninternalproxy,+,Undefined 00000000-0000-0000-0000-000000000000;QueueLength=0

These messages are repeated every 65 seconds for a 15 minute period and then stop.

In Submission we see many more like this:

014-03-12T08:40:36.445Z,08D102BA3F4FE575,SMTP,mailboxtransportsubmissioninternalproxy,+,Undefined 00000000-0000-0000-0000-000000000000;QueueLength=0

These messages repeat every 120 seconds many times throughout the day.

My questions:

(1) If we see the messages in the Mailbox Connectivity Submission log, does that mean that emails we are sending may not be getting to their recipients? (We are not receiving any DNR reports ourselves, just some people sending messages to us, and it's not consistent, i.e., they can resend and we do receive their second message.)

(2) Do these messages appear once for each message that fails, or do they just report in these fixed number of seconds intervals, and that any emails that are attempted to be sent or received during that interval fail? (There seem to be more intended recipients who are getting DNR reports from us than there are log messages in the Mailbox Delivery logs, and the times don't seem to line up well.)

We have ECP configured for Internal and External DNS lookups to our local host first and then our external DNS servers provided by our ISP through our firewall.  I've read that for Internal DNS lookups, we shouldn't look to an external DNS server, might that explain this somewhat random occurrence?

Is there any way to perform address re-writing for BOTH the sender address and the recipient address for all outbound mail? We need to use it in-between two separate mail systems. Or is it just limited to sender for outbound and recipient for inbound?

Single Server SPAM filtering

We recently upgraded to Exchange 2013.  We have a single server setup with transport and mailbox roles on the same machine.  We have noticed a dramatic increase in SPAM and I have started to notice our IPBlockListProviders don't seem to be blocking. I've run Test-IPBlockListProviders and it responds as I would expect with a known blocked IP.  However email still continues coming into mailboxes from that IP.  I've noticed some people stating that Microsoft removed connection level filtering. Is this true? If so how do I use DNSBL to stem the flow of SPAM?

Delivery is delayed to these recipients or groups

I'm receiving the below message when sending external emails to SOME people, but not others.

A few things we've noticed:

  1. Anyone from our company can send emails to this person and it gets delayed (not restricted to one person in our company)
  2. It is affecting multiple domains. The example below is for americaii, but so far we've had at least 15 other people get reported with the same issue this morning.
  3. We can still send to other domains (gmail, other company domains, etc.) without issue or delay
  4. We are on exchange 2010 and using outlook 2010.
  5. We haven't changed anything on our server (no updates, new upgrades or new software)
  6. The receipients (e.g., americaii) can still receive email from other senders without issue.

    -------------------
    Delivery is delayed to these recipients or groups:

    XXXX XXXX (XXXXX@americaii.com) (XXXXX@americaii.com)

    YYYY@americaii.com (YYYY@americaii.com)

    Subject: ###########

    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 22 hours and 52 minutes. You'll be notified if the message can't be delivered by that time.

    -------------------------

    AFTER 24 hours, we get a rejection notice like this:

    -------------------------
    Delivery has failed to these recipients or groups:

    XXXXXX@Grainger.com (XXXXXX@Grainger.com)
    The server has tried to deliver this message, without success, and has stopped trying. Please try sending this message again. If the problem continues, contact your helpdesk.

Powershell Advise required for MessageTracking

Hello,

Im wondering if anyone can help me.  Im getting to grips with the basics of Powershell now but Im attempting to setup a little script that will assist me and the rest of our exchange administrators to pull back quick results from MessageTrackingLog instead of using the EMC Tracking tool of editing a command every time we want to do tracking.  The problem I have is that I wish to use most of the parameters available to the powershell cmdlet 'get-messagetrackinglog' via read-host -prompts.  But if you dont enter data in every one the script doesnt actually work. You just get an 'OK' response. You will see the couple of lines below that im trying to excempt from the requirement of data in the script.

I will paste exactly where I am upto below to try and resolve the issue.  Any assistance is greatly appreciated.....

[System.Windows.Forms.MessageBox]::Show("WELCOME TO MESSAGE TRACKING" , "EMAIL TRACKING")
$server = Read-Host –Prompt ‘Enter Server Name to view Tracking Upon’

Forwarding to Outbound Connectors

Hi Everyone,

Quick question, hopefully an easy solution...

I currently have a rule in place which forwards all mail to user@domain.com to an outbound connector.

This works great, and the end-user receives the email at the connectors end point.

However I would like it so that it keeps a copy of the email in the users local mailbox as well as forward to the outbound connector. I am using Exchange Online (Office365), and can't seem to find any option for this.

Any assistance would be greatly appreciated.

Cheers,
Anthony

Exchange 2013 + Outlook 2013 no domain security symbol green arrow

hello,

we have implemented domain security with a few partner domains. With Exchange Server 2010 and Outlook 2013 or 2010 we see as expected the green arrow symbol for domain security in outlook when receiving mails from the partner domains.

In our test environment we have an Exchange 2013 server.  Here we see the symbol only when using Outlook 2010, with Outlook 2013 we don't see the symbol.

It seems that only when Exchange 2013 and Outlook 2013 in combination is used the symbol is missing, is this a normal behaviour or what can we do to see the symbol? The mails still coming ciphered and you can see the X-MS-Exchange-Organization-AuthAs: Partner in the header of the mails but no symbol is showing.

Thanks and best regards

DNS Configuration for Exchange 2013

I have a stand alone server 2012 with AD, DHCP, DNS and Exchange on it and started getting DDoS attacks

I installed a firewall had to change the subnet of the server from 10.0.0.0/24 to 192.168.1.0/24 and after re-configuring the Servers IP, DHCP and DNS found that I had no incoming email. (invalid Security Certificate)

I found that mail  traffic was directed to the Router instead of Exchange and being rejected with the routers security certificate. I have since fiddled with the DNS so many times I don't know what is right and wrong

Anyone have any ideas where I have gone wrong  what is in the tables that shouldn't be there and what is missing.

email address is user.mail.domain.com

Geotrust SSL Security Certificate is mail.domain.com autodiscover.domain.com server01.domain.com

OWA and Outlook 2013 work incoming and outgoing from within the subnet,  both internal emails and  external emails

But users off site can't log in to outlook 2013 and get blocked with OWA  by invalid security certificate.


**Testconnectivity.microsoft.com results

autodiscover failed

resolved host domain.com successful with both correct IP addresses returned

Port 443 open

SSL Certificate incorrect it is the routers Certificate  not the Geotrust certificate.

I'm trying to configure a transport rule in Exchange 2013 to block all emails from the TLD .eu   We get nothing but a TON of spam that is not caught by the Exchange 2013 spam filter, and it's always from a different domain. I have seen guides for 2007 and 2010, but nothing for 2013.

Do I just use the rule "The sender domain is" and use the value ".eu"? I just want to verify this is the correct way to block a TLD.
