Exchange Server 2013 send error " ... Winsock error code: 10060 "

May 9, 2016, 7:19 am
$

I have added an Exchange 2013 Server to my domain which already has 2 Exchange 2007 servers. Outgoing mail from the 2013 server gets stuck in the queue with the error 

"Failed to connect. Winsock error code: 10060, Win32 error code: 10060, Error Message: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond  xx.xx.xx.xx:25"

The Exchange 2007 server can still send mail out just fine. I have removed my smart-host from the mix temporarily to make sure that it wasn't them by creating a send connector that sends directly to the internet. Some messages will get through initially but the outgoing mail queue fills up quickly with those that do not get sent.

How to avoid duplicate incoming mails

Hello,

I am having a very common issue:

Some users in Exchange are receiving duplicated mails because they belong to a distribution group. When a user sends an email to this distribution group in the FROM field and to their email address in the CC field, the destination users receive the mail twice.

Is it possible to create an Exchange rule to avoid emails to duplicate in destination mailbox?

Thank you

Schannel Fatal Alert 46

May 10, 2016, 4:54 am

Hi, we're experiencing a small issue with our Exchange 2013 system. At present we don't have a load balancer, so our firewall points directly to one our of Exchange servers. Whichever server is set as the recipient of email is bombarded by Schannel Errors (Event ID: 36887) and the following message:

"A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 46."

It would seem this is one error message per received email. If I change the firewall to point to the other server the errors then start on that server.

I've read previous posts which point to having multiple certificates set up but only the current valid certificate is present. The only other certificates on the servers are:

- Microsoft Exchange Server Auth Certificate

- WMSVC

- Microsoft Exchange

These are the self signed ones that are created during installation, I'm assuming they're used internally still for various operations and should not be removed. None of them have our external URLs, but the 'Microsoft Exchange' one does contain the internal name of the server in the CertificatesDomains property.

This issue seems to have coincided with us moving to Mimecast, I've spoken to their support but they're certain it's our issue rather than something at their end. Mimecast do provide the ability to use strict TLS but we don't use this.

I'm aware of a registry setting existing that will stop the errors from appearing in the event log but I think I'd rather solve the issue rather than ignore it!

I'd appreciate any other suggestions, thanks.

Transport rule blocking message - having trouble tracking down the issue

May 12, 2016, 4:46 am

Hi all,

          Exchange 2013 single server environment.

There are a few transport rules in this environment, one of them blocks sending to an "all staff" DL by all but selected senders, including one external "mass-mail" type provider that is used for newsletters etc.

The external provider sends from different hosts, but they always have their company name in the sending domain name - due to this, I have added an exception of "The sender address includes <company name>"

This has been working for approx. 6 months - but recently started bouncing mails - and im struggling to work out why.

The message tracking log shows a sender which should match the criteria, the event data shows the action of reject message...

EventData               : {[AMA, SUM|v=0|action=|error=|atch=0], [AMA, EV|engine=M|v=0|sig=1.219.1551.0|name=|file=],
                          [TRA, ETR|ruleId=2d247558-5b44-40cf-8c7a-d33dbfc7b291|st=12/05/2016 7:49:09
                          AM|action=RejectMessage|action=Halt|sev=1|mode=Enforce], [CompCost, |AMA=0|ETR=0],

When I turn on pipelinetracing with

Get-TransportService | Set-TransportService -PipelineTracingSenderAddress <senderaddress as it appears in  message tracking>

Get-TransportService | Set-TransportService -PipelineTracingEnabled $true

send another test message

The directory that Get-TransportService | fl *pipeline* specifies doesn't even exist.

is there another way of troubleshooting this that I have missed? and any suggestions on why pipelinetracing doesn't seem to be working ?

One Exchange Forest, multiple customers - stop mailflow for some?

Hi

I strange question follows :-)

I have a customer who host mail for several customers.

Recently it has been nessesary to block ALL internet traffic. 

One of the customers are VIP and now they want a sollution that secures mailflow for the VIP even if we lock down the others.

I say, that can not be done. Same Exchange Forest, same send connector, same DNS. I suggest a new forest with a new seperate Exchange installation and then create linked mailboxes.

Any suggestions? Or did I forget something? :-)

Thanks

2 CAS, 2 Mailbox/CAS (DAG), Citrix Load Balancer

In doing the setup of Exchange 2013 we made sure that the internal and external URLs on all 4 servers were the external FQDN. What I am wondering is if internally we pointed the URLs to the internal server mailbox/cas server for that particular AD site if an outage occurred, such a down for an offline defrag, would the DAG route the traffic to the other mailbox/cas server without the load balancer?

The reason I ask, is I think the LB and/or firewalls are negatively impacting the flow of traffic between clients and servers internally.  So if the DAG will failover without a LB, and internal clients will not be affected, I'd prefer to route the clients internally to the internal FQDN of the servers.

DAG responds with Internal URL

When I do a test on MXToolbox.com our DAG servers are responding with the internal FQDN of the server that received the request. When I attempt the change the FQDN on the Default Frontend (servername) I get an error that it can not be changed because Exchange Servers are selected.  Even if I uncheck Exchange servers I still can not change the FQDN.  Having said that I don't really want to uncheck that as I am worried it will break communication between the servers.

How do you get the mailbox/cas DAG to respond with the correct external URL?

Sender not Validated : Mails when sent from another accepted domains

We are running Exchange 2013 with multiple accepted domains.

We are stuck with some external recipients reporting that mails sent from 'Domain B' are going to SPAM folder with the reason as "sender not validated' 

We have single send connector with HELO response  FQDN set as the primary default domain (Domain A)and all other accepted domain mails  using the same connector for sending mail. We are using a wildcard certificate as *.domainA.com.

One option may be to define another send connector with Smart host and HELO responce FQDN as that of Domain B so that emails sent from Domain B users,  take a different route with different source address and reach gracefully.

Is their a better way doing this without involving Smart host

Email flow betwen On premises and Exchange online

Dear Folks,

A customer is running with Exchange 2010 SP3.  for outgoing emails, it submits emails to Smart Host and for Incoming emails it lands to Yahoo as MX points to Yahoo DNS and through a POP utility, On Premises Exchange fetches emails.

Now,  we have introduced Hybrid Exchange in the environment and we have moved couple of test mailboxes to Exchange Online. After this change

On premises users can send emails to Exchange Online users but Exchange Online user can not send email to On premises users

Similarly, Exchange online users can send email to hotmail, yahoo but can not receive emails from hotmail/ yahoo/ external domains.

please note we needed to modify Inbound/ Outbound connectors to define yahoo MX and our Smart Host IPs.

please assist what else do we need to consider?

Thanks, Sheeraz

Messages Rejected by some Spam Filters

We have Exchange 2013 in production. Recently some users complaining about their email delivery. Some of the external domains just rejected our email and by this we didn't get any bounce back messages. Other way is to call their IT and ask them to white list our domain, this works. But I need permanent solution. I went MX toolbox and did SMTP test and it returned "Reverse DNS is not valid Hostname". I searched about this and found to call ISP to make PTR record for Public IP. I called and they already have.

Domain: example.com

Public IP: 1.1.1.1 (I called ISP and they told PTR record already exist)

Can somebody help and suggest what can be done or what kind of specific records I have to make ?

Thanks

Hardening Exchange 2013 Hybrid Receive Connector

Hi,

When creating a hybrid deployment you are required to configure a recieve connector so Exchange online can send E-mail to Exchange on Prem.

How do I secure this connector so that only office 365 can connect (and not a spammer for instance).

Thanks
