IIS SMTP Relay

May 7, 2014, 8:07 pm

We are using windows server 2008 Server R2. We installed IIS and the SMTP relay component. It is setup to relay mail to our exchange 2010 CAS server. All internal mail is relaying properly on this server to the exchange 2010 CAS server to internal email addresses. When someone tries to send to a recipient outside the organization such as to domain name hotmail.com, gmail.com microsoft .com, it does not relay the message. When I check the logs it looks like it does not even relay the external email address to the cas server.


The error message we get is below. Please assist in what is wrong.

Delivery has failed to these recipients or groups:

gogear22@hotmail.com
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.

Restricting Incoming Mail to deliver during office hours

May 12, 2014, 12:15 pm

Hello

Can you restrict Exchange (2007) in my case to deliver email to users during certain hours of the day.

Currently we have several users asking as they are getting email coming into their phones late at night or in the early hours of the morning.

They want to leave their phones on and not have to keep disabling emails on phones when they go to bed or example so I wondered if there was something we could do on the server to only allow mail to be delivered during certain hours of the day on the connectors.

Help appreciated

thankyou

Messages stuck in "Retry" in Submission Queue - Exchange 2013

Hello,

We have 2013 Exchange consisting of 2 CASs and 2 MBX servers spanning two locations via VPN, 1 of each server in each location. We are hosting exchange for an outside domain, and have just transferred them into our organization within the last month. There are two users who consistently have messages stuck in the "Retry" status in the submission queue. Not all of their messages, but usually 2-4 are stuck and eventually kicked back to them. 

I have read other forums about a potential issue with conversion to RTF. I have forced the queues empty and attempted this fix, but within a week the users had messages stuck again.

Has anybody run into this and possibly found a fix?

outbound email IP address returns firewall ip not mx record ip

Hi all,

We are sending emails fine but some are rejected from some SMTP domains withy the message below:

'450 4.7.0 Proxy session
setup failed on Frontend with '451 4.4.0 Primary target IP address responded
with: "554 5.7.1 Delivery not authorized no reverse DNS record exists for
your connecting IP address." 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 ....

I searched on the outbound email IP from one of my sent emails to an external email and it was not the MX record IP, it was the firewall IP that is why it is blocked (as some email systems check for reverse DNS entry that points to your email server and the firewall do not have one in public DNS). My question is how to solve this? Is it by simply adding a RDNS record in public DNS for the firewall IP to point to our mx record or changing the route traffic on firewall? What are all our options?

Note: SPF wizard states that there is no SPF record found but there is an A and MX record currently exist for this domain (our SMTP domain)

How do S/MIME and IRM work together? Can you have users sign and or encrypt their messages with S/MIME and then also have some IRM policies in the background? I'm not sure of the exact scenario, but in general can these two technologies work well together?

Exchange 2013 Address Book Policy Routing Agent Issue with Mailboxes Hidden From the Address Lists

When the AddressBookPolicyRoutingEnabled attribute is enabled by running Set-TransportConfig -AddressBookPolicyRoutingEnabled $True, I am having an issue with delivery failures for mailboxes that are hidden from the address book. I receive the following undeliverable message:

'532 5.3.2 STOREDRV.Deliver; Missing or bad StoreDriver MDB properties'

If I disable the AddressBookPolicyRoutingEnabled attribute by running Set-TransportConfig -AddressBookPolicyRoutingEnabled $False then emails are successfully delivered to the mailbox that is hidden from the address list.

I followed the installation instructions here: http://technet.microsoft.com/en-us/library/jj907308(v=exchg.150).aspx

Below is the status of the ABP Routing Agent on my Hub Transport/Mailbox server:

Enabled: True

AssemblyPath: C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\agents\AddressBookPolicyRoutingAgent\Microsoft.Exchange.Transport.Agent.AddressBookPolicyRoutingAgent.dll

Relay Receive Connector - Recipient Limit is not respected

Hi,

I have configured a Relay Receive Connector for an application and I set the Recipient limit for it, 50 recipients.

Unfortunately this limit is not being respected, the application can send emails to about 70 recipients without block the message.

I have a Receive Connector for my users and it is working well.

My question is, is any kind of difference when a relay receive connector is configured or it is a bug?

Thanks in advance.

Best Regards.

Exchange Anti-Malware and Trend Micro

Hellow,

I am finalizing an Exchange 2013 deployment and I have a question:

I have installed Trend Micro as the anti-virus solution for my exchange servers, but this is a file-level protection software, I guess it doesn't protect my Exchange, rather it protects only the windows server environment.

Should I enable the Exchange 2013 built-in anti-malware protection along with the trend micro? If it´s not recommended, which one should I choose to keep?

Thanks in advance.

Can't realize how to configure Receive connectors

There is a number of servers:

All of them Exchange Server 2010 SP3 RU5

EDGE Server - EDGE role

Exchange10 - Roles: Hub Transport, CAs, Mailbox, UM

Exchange10s - Roles: Hub Transport, CAs, Mailbox, UM 

Now I installed Exchange 2013 with roles CAS, Mailbox. Firewall disabled.

There are 5 default receive connectors on it. How can i configure them for mail flowing between each other and to the internet throw the EDGE?

I tried to send messages from all servers and from internet. Default connectors don't work because messages stuck into the queues of EDGE and Hub transport Exchange10

I tried to disable default connectors and make my own (with restart services), but result is the same.

My own receive connector were with these parameters:

AuthMechanism    : Tls, Integrated, BasicAuth, BasicAuthRequireTLS, ExchangeServer
RemoteIPRanges   : {::-ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff, 0.0.0.0-255.255.255.255}
TransportRole    : HubTransport
PermissionGroups : All permission groups

Cannot enable custom DSN

Hello,

I am trying to create a custom DSN to send a NDR alerting the internal sender that his/her mail has been rejected due to profanity.  I created a DSN 5.2.9 with the message "Your message appears to contain profanity or unprofessional language - please correct before re-sending"  However, when i try to apply the DSN to the rule I get "The value that you entered cannot be saved because it contains the character "5".  To save this, you must first configure a custom delivery status notification.

What am I missing that would cause the server not to recognize that there is a custom DSN?  Note that from powershell, the server returns the correct message when I enter Get-SystemMessage.

RecipientThreadLimitExceeded in message tracking logs, queuing and holding up local email delivery to office365

May 15, 2014, 9:04 am

Please let me know if anyone knows an answer to this one... We're in a Hybrid Exchange environment, with 2 x Exchange 2007 servers,  and 1 x Exchange 2013 Hybrid server which is pointing to Office 365 for the purposes of relaying mail to O365 while we migrate our users out there.

We have just finished migrating, but just a couple of days ago we started experiencing delays in email delivery to O365... Not all mail, but some!  Incoming email or locally generated email gets relayed out through the Hybrid server and out to O365, but not all email is delayed... only some, but it's constant.  During the busiest part of the day, about 200 messages are sitting in the Queue in Exch2013... but they all eventually resolve between 5 and 45minutes.  The users are not happy.

The last error in the queue viewer for each hung email reads:  451 4.4.0 Temporary server error.  Please try again later.

If I look at the message tracking logs, I find an interesting item -- "RecipientThreadLimitExceeded":

2014-05-15T14:15:51.608Z,192.168.3.11,hydra,207.46.163.215,company-mail-onmicrosoft-com.mail.protection.outlook.com,RecipientThreadLimitExceeded,Outbound to Office 365,SMTP,DEFER,10307921510617,<5E5E05B0073A514AA6D072AFB5EB8182276370A4@APSWP0475.fubar.com>,885ea3ce-a020-41b1-8950-08d13e58d6d3,JoeUser@company.mail.onmicrosoft.com,451 4.4.0 Temporary server error. Please try again later,10117,1,,,Read: This is your generic subject line,sender@fubar.com,sender2@fubar.com,2014-05-15T14:16:51.608Z,Undefined,,,,S:Microsoft.Exchange.Transport.MailRecipient.RequiredTlsAuthLevel=Opportunistic;S:Microsoft.Exchange.Transport.MailRecipient.EffectiveTlsAuthLevel=EncryptionOnly;S:DeliveryPriority=Normal

I have tried to find some documentation on resolution for this RecipientThreadLimitExceeded error, but I can only come up with some Exchange 2011 documentation which recommends adding some entries to the EdgeTransport.exe.config file to bump up the RecipientThreadLimit value... I have not found anything pertaining to 2013.  I cannot even find any powershell commands to see what the current RecipientThreadLimit is on 2013!  Aghg!

Has anyone seen this before, or have any recommendations?

Thank you,
Mike

Hello,

I have an on-premises environment where I have an exchange 2010 hub and edge server. I have 4 domains. All my emails are routed through edge server to the internet. When I send an email from my primary domain to a particular remote domain the email gets delivered. When I send an email from any other secondary domain the email does not get delivered at the remote end. The remote domain is on office 365. 

I tried sending the email with the delivery receipt to the remote domain from my secondary domains and I always get the delivery receipt stating that the email has been delivered however the remote domain admin says that the email was never received by him. We have also did the message trace on Office 365 remote domain but there was no trace of that email.

Please help and let me know how can I proceed futher this is hampering the productivity in my organization.

Hello there in Exchange forums.

I have Exchange 2010 server with all current patches and SenderID action set to reject if SPF fails. If the domain is using keyword include in their SPF TXT record (such as account.microsoft.com where for example onedrive mails come from), the sender ID fails with 550 5.7.1 Sender ID (PRA) Not Permitted, instead of accept message.

Do anyone resolve that?
