Hi,
I have a 2013 installed and working - both with incoming mail and outgoing mail when using Outlook and similar clients.

No problems sending mail from and to either internal or external domains. However, I want to authenticate with the standard SMTP server with a username + password and send e-mail using "standard clients".

I cannot get this to work. In code, when I authenticate through SMTP (user/pass) and tries to send an email from "user@mydomain.com" to "user@anotherdomain.com", I get the error:

Mailbox unavailable. The server response was: 5.7.1 Unable to relay.

I don't really know how to set this up to get it working. In an existing Exchange 2007, I had no problem setting this up, but I cannot get it to work in 2013. If I add "*" to accepted domain, it works, of course, but that gives me an Open Relay.

I have a default send connector, mapped to the SMTP domain "*".

How do I configure so that all authenticated users can relay freely?

Hi,

I have new testing lab to play around with which is starting to drive me insane. I have exchange 2013 and outlook 2013. I can receive emails from external domains but I am unable to send emails internally or externally!

Now I would know what to look at if I couldn't send externally, But not being able to send internally has completed confused me!

anyone got any tips where to start troubleshooting for not being able to send internal mail? Once internal mail works I should then be able to get external mail working as well....

Thanks

When i send a email with the attachments to the external and internal members it goes fine. After that when i resend the same message with some modifications getting undeliverable message stating "The recipient could not be processed because it would violate existing security policies #MSEXCH:MSExchangeIS:/DC=com/DC=mydomain:SERVERNAME[578:0x000004DC:0x0000001D] #SMTP"

Any one can suggest me what does it meant?

Hi Guys

Just done an Exchange 2003 to 2010 migration and cant get the 2010 server to receive new email, I can see this a common problem everyone is having and have looked through all posts and cant find the right answer.

I am able to send email its just the receiving part, I have done the following

• Set receive connectors to allow anonymous users
• Removed routing group connector
• Set the port forward on my firewall
• Created send connector which works fine as able to send mail

I have noticed on my exchange 2003 box there are some emails saying "Messages with an unreachable destination" these seem to be the mails I’m sending

can someone help?

Hi,

Only found this link, which I am not allowed to post :( which is leading me to assume that RBL is not possible on exchange 2013 in a single server installation.

I really do not hope that this is true, would be a shame to not have such an important feature.
Can someone point me to a microsoft article detailing this missing feature.

Br,
Jan

I'm migrating from Exchange 2007 to 2013.  I currently have two mailboxes moved to the Ex2013 environment simply for testing.  We are using a Symantec.Cloud service for email encryption.  I have my send connector configured with the Symantec smart host for outbound email and my outbound mail tests successfully. 

I cutover my firewall to the Ex2013 server so I could test services before migrating the remaining mailboxes.  Everything works except inbound mail.  It's my understanding that the default receive connectors should be configured by default to receive mail.  I have also contacted Symantec.Cloud to verify that they have no knowledge of our internal servers.  MX records are pointed to them and they simply hand off to our public IP address.  I verified that my NAT rules are in place so Ex07 and my Ex13 servers both resolve to the same outside IP address. 

I can send internally between the two mailboxes that have been moved.  I can also initiate a manual SMTP transaction from the command line and that delivers to my test mailboxes.  So to be more specific it is the inbound mail FROM the outside world that does not work. 

I've read other posts with mail flow issues and people are always asked to run the connectivity analyzer and test inbound or outbound email but obviously with the Symantec.Cloud service in place this option doesn't exactly work for my troubleshooting. 

I do have split DNS but I've configured the appropriate DNS zone internally and I have successfully tested OWA, ECP, and Autodiscover internally and externally. Still no inbound mail flow from the outside world. I can also see in my firewall that my smtp rule is getting hits so Symantec.Cloud is still handing off email.  What could I be missing that would prevent my Ex13 server from receiving email from the firewall?  Also, if I go to my firewall and switch my inbound smtp rule back to the Ex07 server then try to send to my test mailboxes, that gets delivered successfully. 

Hi!

I just tried to configure domain security in Exchange 2013 in a test environment: two messaging organizations, each running a dedicated client access role and a mailbox server role. 

Domain security seems to be configured correctly - recipients running Outlook get that additional icon which says that the email 'was received securely'. In that scenario the mailbox server is sending the mail directly to the recipient domain. So no proxying via the local client access server takes place.

When I try to use the domain local CAS as proxy (Set-SendConnector -FrontendProxyEnabled $true) the mail stays in the mail queue. The LastError on the queue states: '... 451 4.7.3 The admin has temporarily disallowed this secure domain...'. The protocol log of the send connector states: 'Message to secure domain 'dom1.test' on send connector 'Outbound Proxy Internal Send Connector' failed because DomainSecureEnabled was set to false.'

I have no clue where that internal send connector could be configured. Or where the 'Outbound Proxy Internal Send Connector' can be seen.

Or is domain security just supported without using the frontend proxy?

Many thanks in advance!

Greetings,

Nils

Hi,

We moved from exchange 2010 to exchange 2013, we need to configure mail relay connector so that exchange 2013 could receive emails coming from different sources (printer for scan to email, sharepoint....)

I followed an article to create a receive connector for that, I allowed anonymous users (even if on sharepoint and the printer we provide credentials for authentication), We also added the IP addresses of the printer and sharepoint on this receive connector.

It starts working, but after few hours or minutes (it's really random), it just stops working, I looked on error on exchange event viewer, and I found this: 

Warning event id 1035 : Inbound authentication failed with error LogonDenied for Receive connector Default Frontend ExchSrv. The authentication mechanism is Ntlm. The source IP address of the client who tried to authenticate to Microsoft Exchange is [Printer IP Address].

From the message I see that the receiver was "Default Frontend ExchSrv" and it is a "FrontendTransport" role. But my receiver I created is a "HubTransport" Role.

I went to the receiver "Default Frontend ExchSrv" and I enabled "Exchange Users" , it started working again. But I don't know for how long.

My question really is that on documentation for the mail relay for printers, It was mentioning to create a receiver with HubTransport role, but it seems it's the FrontendTransport role receiver that is receiving the request. Can someone explain this scenario to me? Do I still need the mail relay receiver I created?

Thank you.

Hello All -

I recently migrated our company to Exchange 2013 and noticed that our email was leaving through the mailbox server. I put a check mark in the Send Connector where it says "Proxy through Client Access Server" and my mail is still coming from the mailbox server. How can I go about fixing this problem?

Environment:

1 CAS Server
1 Mailbox Server

Both server are behind the firewall with only port 25 opened to the CAS. The CAS has a Send Connector to a smart host for all messages.

Thank you!

Ryan

Hi,

E2K13CU1 with default settings added to working existing E2K10SP3 organization.

Mail doesn't leave Drafts folder (sent form OWA).

Telnet to server at port 25 responds after MAIL FROM: with:

421 4.3.2 Service not active (exactly - didn't found anything like this anywhere)

I checked DNS (also set custom DNS config in E2K13 ecp, all services are running, no custom AV, no low disk space, no events.

Thank you

Richard

Current configuration - Exchange server 2010 retrieves email, distributes incoming email to mailboxes, sends outgoing mail out, shares calendars and contacts, allows OWA users to login for email, also external users VPN into the LAN and pickup their emails through Outlook when attached through the vpn.

Would like to disable the retrieval, distribution of email by the exchange server, also the OWA feature. Keep the contact and calendar sharing, and use the exchange server to backup our outlook clients.  On the outlook clients add a pop3 client as the default account that would send/receive emails, and keep them in the exchange mailbox.  Exchange would become a secondary account in the Outlook account settings. 

Does this sound possible? If so how would you proceed?

Hi guys,

I have an Exchange 2007 and 2013 coexistance scenario. I have an Edge Transport, with FPE, and a HT/CAS in Exchange 2007 with SP3 and CU1.

In Exchange 2013 I have 2 CAS and 2 MBX.

Just now I am running tests from my Edge server, checking delivery to a Mailbox Server in 2013 using Telnet. However, I am seeing in the message delivery logs 5.7.1 "Client was not authenticated" when the message is attempted to be sent to the Mailbox server.

EdgeSync is apparently working fine.

Thanks for your help!

Hi,

I have a strange problem, I have installed Exchange Server 2013 CU1 as First Exchange server into my Server 2012 AD environment on a separate server. My problem is:I cannot send mail to myself or any internal users. I can send external mail.

--When I send mail in delivery reports

Hello

I am having a problem with Exchange 2013 outgoing email not being received.  I have set up the send Connector.   The outgoing email looks likes it sends.   It even goes into the sent folder and I get no errors back.

I am aware that RBL blocking depends on the connection filter and we have lost this great feature in Exchange 2013.

Small and mid-sized orgs found this an amazingly effective way of blocking spam, and reducing server load.

Does anyone know when this feature might be re-introduced?

Exc2010 SP2 RU4v2

last night at around 1:30a both of my CAServers logged the following with 1 hour difference ... and outlook would not/open connect to CAS and OWA page would not launch.  We have SCOM2007r2.

Rebooting both CAServers WORKED!!
