Problem relaying to one of our domain after changing public IP.

After changing our public IP we are having problem relaying to one of our domains. Our on-prem exchangeserver (used only for relay) get the following error in the message queue.  

"Last Error: 451 4.7.500 Server busy. Please try again later from [x.x.x.x]. (AS77713200) [HE1EUR04FT016.eop-eur04.prod.protection.outlook.com]". 

It's a scanner that have worked fine prior to the change of public IP change but now all mails from this scanner now gets stuck at  our on-prem Exchange server. Outlook klients have no problem and scanners that send mail to our other domains.

- We have updated our SPF records for all domains.

- Tried to create a IP whitelisting in O365 when sending from the relayserver.

Hi we have problems with Out of office and DMARC, the return-path is empty so the out of office message going straight into the spam/junk folder of hotmail/gmail etc.

I have googled for a solution to this issue, but just found that people solve the problem with third party software / appliances.

Anyone had the same problem and found a solution?

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 being refused by Gmail due ti ipv6 in mailheader

September 11, 2013, 1:40 am

Hi

Gmail is rejecting mails because of ipv6 information in the mail header (exchange 2013). I have read some threads saying that I could do a reghack do disable ipv6. But I have also read that Exchange 2013 depends on IPv6 - so disabling IPv6 could cause other problems in mail routing. I have reverse PTR on ip4. I dont have the option to create SPF records.

So what can I do to prevent Exchange 2013 from adding IPV6 info to the mail header?

Regards

Internal CAS Servers servicing clients despite being behind a Load Balancer

October 4, 2018, 9:05 pm
$

Hi Everyone,

We have 10 CAS servers, with the OA and Autodiscover URL going via a load balancer, which redirects to the 10 CAS servers.

We recently put in an additional two CAS servers, and set the relevant URLs to go via the Load Balancer. We intentionally didn't add these CAS servers to the load balancers to avoid connections at this time while we perform some additional work.

However, it appears that internal Outlook clients are picking up the new CAS server despite picking up the LB URLs. The external clients, which cannot use SCP, do not use the new CAS servers.

I'm not understanding how this is possible? I was of the impression that Outlook retrieves the SCP record, which points to the LB URL, and then it should go to the designated CAS servers.

Can anyone shed some light on why this might be occurring? With the SCP records, does it pass the connection off to a local site CAS server despite the LB by design? 

Cheers!

Mail Relay stops working, have to reboot every 6 hours

We have a service that relays voicemail to email for several domains. After working fine for years, suddenly it stops working about every 6 hours (about every 10 hours during off hours). Rebooting resolves the problem for another 6 hours. The Event Logs don’t seem to provide any guidance. It seems like TCP quits working until the reboot. I’m not sure how to troubleshoot. I can telnet locally or remotely to port 25, until after about 6 hours I cannot. Everything else seems fine, but no TCP port 25 activity. When I do netstat find /i and it is working, it shows LISTENING, ESTABLISHED and a process number. Then that process shows Edgetransport.exe the process number, then 0 and 180,468 K. When it has failed, netstat find /I returns a blank line. I cannot stop the Transport service - it fails to stop.

Any suggestions on resolving or troubleshooting I would appreciate.

It is Exchange Server 2010 on Windows 2008 R2 and has worked for several years.

It passes external tests for Open Relay. (Not an Open Relay)

Thank you

Hi

I've a problem with connection to Exchange 2016 when users are outsite. Inside company (LAN connection) when users run outlook 2010 or 2013, there is no problem with connection to server. When they are outside and run Outlook they gets password prompt window. If they fill in password, the conection is established. Users have to change password for every 30 days so they can't use option "Rememner password".

What is the problem? Please help.

mail flow delays

i have a few emails being delayed from an external sender (only that i know of but could be others).

it hits my mail MTA at 9:02.

immediately i see a return message in the MTA logs from my load balncer VIP IP sayin DSN 4.0.0. message deffered

at 9:21 is see the message queued message in my MTA logs

on the exchange 2013 server, message tracking logs show the message was received at 9:21 and then delivered. i dont see any mails with defer status or any other eventIDs for the delivery of the mails apart form standard ones.

any ideas on where i can look. most external domains can deliver with no delays. this message did have a attachment., but i presume the AV scanning in 2013 is done in the transport pipe line so a delay would should up in message tracking.

SMTP relay to Exchange Online

October 9, 2018, 12:06 am

Hello TechNet,

We have 4 Exchange 2013 servers configured in hybrid mode with Exchange Online. All mailboxes have been migrated to the online service and the MX records points to Exchange Online.

The purpose of the on-prem servers is for management and SMTP relay for printers and applications.

When we send e-mails to distribution groups that are not synchronized from AD or public folders that wasn't migrated (they were created in Exchange Online) via the SMTP service on-prem, they get discarded with a 550 5.1.1 RESOLVER.ADR.RecipNotFound message.

I suspsect that this is related to how accepted domains and send connectors are configured in Exchange 2013, and I would be very grateful to get some input on how to configure this correctly for our scenario.

- Our default mail domain (xxx.com (no not actually)) is configured as "Authoritative" on-prem, and as "Internal Relay" in Exchange Online.
- The scope of our send connector "Outbound to Office 365" only contains "xxx.mail.onmicrosoft.com".

What I would like to do is to re-configure our default domain to "Internal Relay" and add xxx.com to the scope of the Office 365 send connector.

My concerns are that this will break mail flow in any way or that it may cause an e-mail loop when sending to non-existing addresses.

Any input on this matter is greatly appreciated.

Reconfiguring SPF record for more than 13 cloud email sending service provider?

I need some help in reconfiguring the SPF record issue in my currentdomain.com like below:

v=spf1 include:mailgun.org include:sendgrid.net include:amazonses.com include:surveymonkey.com include:spf.protection.outlook.com include:servers.mcsv.net include:mailcontrol.com include:modulargateway.com include:cloudservice.com ip4:202.89.252.19 -all

When using this service: https://dmarcian.com/spf-survey/

I can see the result is:Error: Too many DNS-querying mechanisms (count=13)
13 / 10 DNS-querying mechanisms/modifiers to resolve the record
72 netblocks are authorized
804,283 individual IPv4 addresses

So how to fix this issue to allow my email domain.com to send out the emails with no problem of being blocked by the other client/receiver antispam engine?

The Marketing team wants to use Reply-To Shared mailbox as MKT.Team@domain.com --> Using MCSV
The Product-A team wants to use Reply-To Shared mailbox as Product-A@domain.com --> Using MailChimp
The product-b team wants to use Reply-To Shared mailbox as Product-B@domain.com --> Using Amazon AWS (SES)
....
The product-z team wants to use Reply-To Shared mailbox as Product-Z@domain.com --> Using 3rd party senders....

Thanks in advance.

"Spambox" Folder in Outlook

I've got a user that has been having a weird issue for months that I just found out about but also can't figure out. Please note even though we're currently in a Hybrid configuration this issue existed before migrating his Mailbox to O365 and continues to exist post migration.

User is not having issues receiving email into his Inbox, except for one sender who is also part of our organization. The emails are not going into his Junk Email folder but rather into "Spambox." When one user emails him the email arrives into his Inbox for about 3-5 seconds before it is moved into Spambox. There is no Not Junk or other such options when you right-click in the folder to try and 'whitelist' the one sender. If you move the email back into the Inbox it is moved back again after a few seconds. This happens in OWA, Outlook 2013 and 2016, and his mobile device.

What have I checked?

  1. Spam Filter settings on Exchange Online itself
  2. Checked for anti-spam add-ins in Outlook, none found.
  3. Checked for anti-spam programs in Installed Programs, none found.
  4. Verified he has no additional Mailboxes or Email Accounts added.
  5. All other folks tested, both on-prem and Exchange Online Mailboxes, emails are delivered into the Inbox.
  6. Created new Windows and Outlook profiles on a blank computer, issue still occurs.
  7. Renamed the Spambox folder. This only had the email not show-up until renamed the folder back to Spambox and then the email showed up in his Inbox and was quickly moved to Spambox.
  8. No other user's reporting this problem and no other user's have a Spambox or Unwanted folders in either Outlook or OWA.

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?

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.
