Question on connecting a SMTP server to Exchange 2013

I have a 3ed party software that has a built in SMTP server that coworkers want to use.

However, there is no where to input credentials to access a mailbox within that server.

Therefore, User A can use it to send emails from User B's mailbox.

Are there any settings in exchange to prevent this?

This is all I have to work with in the 3ed party software.

Thanks!

Sending Mail to External INTRANET Domain

August 23, 2018, 12:05 pm

I have an on-premise setup consisting of two 2013 Exchange Servers in a clustered DAG.

Recently a sister organization has requested to be able to send mail to us from their mail server, and also have our users be able to email their users back to their mail server.

IMPORTANT - We are in an INTRANET configuration, with direct access between our sites and no INTERNET connectivity. Both sites have their own Domain and their own Mail Servers.

On our domain, our mail domain is the same as our domain name:

Domain name = mydomain.com

Example mailbox = user1@mydomain.com

For our sister domain:

Domain Name = theirdomain.com

Example mailbox = user1@weloveemail.com

I am attempting to set up a Send Connector on our side so that our users can email our sister organization, and the emails keep getting stuck in the queue: "A matching connector cannot be found to route the external recipient"

What I have done:

- Set up an Accepted Domain for "theirdomain.com"

- Set up a Send Connector for *.theirdomain.com

- Restarted Exchange services, as well as Restarted the servers completely

Additional Info - we have a conditional forwarder to our sister domain - "theirdomain.com". I can ping their mailserver mail.theirdomain.com just fine.

What I have also tried:

- Set up an Accepted Domain for "theirdomain.com"

- Set up a Send Connector for *.weloveemail.com

- Restarted Exchange services, as well as Restarted the servers completely

Any help/advice is greatly appreciated! I have looked up multiple articles online including Practical365, etc.

Exchange 2013 junk e-mail filter with safe senders list bug?

October 17, 2018, 4:20 am

Hi,
We've got unwanted experience with Exchange 2013 mailbox junk e-mail configuration. We've setup an account junk filter settings, that accept e-mails only from senders from safe senders list, with command: 

Set-MailboxJunkEmailConfiguration -Identity "Our Mailbox" -TrustedListsOnly $True -TrustedSendersAndDomains $ListOfEmails

Generally it works fine - if e-mail is sent by sender who is not on the list, that e-mail goes directly to junk e-mails folder. But there is one strange exception - if sender who is not on the list add e-mail address that is on the safe senders list as CC, that e-mail will be accepted and placed in Inbox folder. 

Is there any option or fix to change that behaviour?

Thanks fof help.

Hello All,

I have Exchange Servers 2013 CU 13 in my environment and I have created a new website in the IIS to create new owa, ecp virtual directories to user login from internal and external networks. I am planning to upgrade to the Latest CU. As we all know that the new CU upgrade means installation of exchange from scratch. In my case do I have to re-create the new website again after I upgrade to the new CU or will the new website (owa and ecp virtual directories) be available even after the CU upgrade.

Cannot Update Office 365 Default Email Address Policy for Distribution Groups

October 24, 2018, 3:55 am

Hi,

We are running a hybrid of Exchange 2013 and Office 365.

We have just added a new domain to our emails, I did this on our local Exchange Server, and then ran the hybrid config tool to push the new domain over to office 365, also added the domain to office 365 and verified it.

Emails are flowing fine on the new domain, and users have the domain as an email address.

Local Distribution groups also have the new domain attached, and are working.

But... the distribution groups that exist only in Office 365, do not have the new domain attached.
If I went to create a new group there is an option to create with the new domain..

But, I cannot figure out how to add the new domain to the exisiting groups.

I have run this command on an Office 365 connected powershell:

Set-EmailAddressPolicy -identity "Default Policy" -EnabledEmailAddressTemplates "smtp:..."

But it just returns: You are not authorized to perform this operation on e-mail address policy "Default Policy"

and I am connecting using Office 365 Global Administrator account.

Does anyone have any ideas how to add the new domain to the exisiting groups, without manually updating all the groups.

Thanks,

Tim Jeens

Exchange mails do not reach Office 365 users

Hi,

We have a hybrid set up of Exchange 2010 and Office 365. If this is not the correct place to post this, please move to the necessary place.

We have added a new domain(domain5.com) in Office 365. We have the same domain in On Premise Exchange also. We have then migrated an on premise Exchange user abc@domain5.com to Office 365. This migrated user can send mails to on premise Exchange. But the reply will not reach Office 365. Exchange on premise users cannot send any mail to this migrated user also.

The mail when tracked reaching one of the on premise hub cas server and staying there.

The migrated user can send and receive mails to other Office 365 users and also other external domains.

Please let me know the steps to resolve this issue.

Email Jam in the Journaling Queue

We have random emails mostly, it looks like just spam that keep getting jammed up in the "Journaling Queue" with the following error;

“Last Error: 400 4.4.7 The server responded with: 550 5.6.2 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA. The failure was replaced by a retry response because the message was marked for retry if rejected.”

I have followed the "Bare linefeeds clogged" question earlier and I'm continuing to get these messages on a daily basis even after changing the BareLinefeedRejectionEnabled to $true.  These were the connectors that I updated (which are all of them)

  • FrontendTransport
    Set-ReceiveConnector "FSRM-SMTP" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "SERVERNAME\Client Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector -Identity "SERVERNAME\Default Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true
  • HubTransport
    Set-ReceiveConnector "Client Proxy SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "Internal-Relay" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "SERVERNAME\Default SERVERNAME" -BareLinefeedRejectionEnabled $true
    Set-ReceiveConnector "Outbound Proxy Frontend SERVERNAME" -BareLinefeedRejectionEnabled $true

I have to manually "Remove (without sending NDR)" and I would like to find a resolution so I don't need to monitor and worry that emails are jamming up in this queue anymore.  Any ideas?

Mails Are getting stucked into submission queue-Can Not open the mailbox /o=/ou=exchange.......cn-microsoft system attendant

We have suddenly observed that some mails are getting stucked into submission queue.Upon analyzing the sender and recipient of the mails got stucked on the queue we have identified that recipients of those mails are located on a particular exchange database. 

We have observed an error "Can not open the mailbox /o=<orgname>/ou=exchange administrative groups......../cn=microsoft system attendant  while trying to open any of the above mailboxes from ECP console whose mails got stucked in queue.


Not everybody of the same database was having the issue of mail got stucked in queue or "can not open the mailbox....".So it may not be a db level issue.Also some other database mounted on the server was not having the same issue.So this may not be a exchange server level issue.

None of the database are showing dismounted also..All are mounted.

But out of the mails which got stucked in the queue; all the recipient had the "can not open the mailbox.....Microsoft system attendant" error.

I have tried to move the effected mailboxes to some other database but those are not getting moved also. 


What can be the issue...Please advise me....Please let me know in case of anything needed.

Duplicate emails being received after restarting Exchange transport services

Hi Team,

We have an in house application server which is integrated with our exchange 2013 server, we have added the IP of  the application server on receive connector to send emails , recently for some maintenance work we had to restart the Microsoft exchange transport service couple of times on the mailbox server where the receive connector is created.

After restarting the service we have found lot of duplicate emails are being generated, not sure if it is because of the exchange server or the application,i feel its because of the exchange server as we paused and restarted the transport service couple of times after which this issue started.

When a customer from one company tries to email us, the email is not delivered and the customer eventually gets an NDR that shows the email failed with the following:

Status: 4.4.7
X-Supplementary-Info: < #4.4.7 SMTP; 403 4.7.0 encryption too weak 0 less than
 128>

The customer is saying that our mail server is the problem.  Our mail server is a Windows SBS 2011 server with Exchange 2010 w/SP3, rollup 22

What do I need to do to receive these emails?

Thanks,
