Send connectors to different smart hosts

May 13, 2015, 12:29 pm
$

We have multiple clients in our multi tenant hosted Exchange.  Is there an easy way to setup different smart hosts for each client?  Right now it is either outbound through the MX record or a smart host.  We can setup a send connector to route to a specific domain, but I would like to define the internal domain to use a specific smarthost.

Example

we hold these domains

ABC.com

XYZ.com

DEF.com

I want this to happen

ABC.com - smarthost - trendmicro.com

XYZ.com - smarthost - barracuda.com

DEF.com - smarthost - spamassassin.com

Thanks

X.400 addresses and IMCEAEX NDRs

I admit this has been in my "If you don't look at it funny, it will not mess with you" category.  However after having some interesting conversations at Ignite last week I decided to go back and look at this.  

Occasionally I have a user that reports the "IMCEAEX" NDR.  I have always had them delete their address autofill cache and the issue was resolved.  Our mailboxes have X.400 addresses assigned.  They have been there since I took over the environment.  There are no X.500 addresses.

I ran the following to see if there are issues I was not aware of:

Get-TransportServer | Get-MessageTrackinglog -EventID FAIL -Start (Get-Date).AddDays(-7) -ResultSize Unlimited | Where {$_.Recipients -match "^IMCEAEX*"}

This returned a large number of results.

My question is, do I need x.400 addresses?  Should they be x.500?  Would removing the x.400 resolve these NDRs or possibly make it worse?

I installed Exchange 2013 CU8 and now everything seems to work fine except I have NO mail flow! Mailboxes can be access by ActiveSync, Outlook and on the OWA website. Mail appears to send without any errors but messages are not going out and they are not being received either. I send messages internally and they're never delivered nor are messages sent to myself. Can anyone shed any light on this? Thanks in advance!

Forwarding Mail to External Addresses - How can we Avoid Triggering Spam Blockers on Legitimate Mail?

May 16, 2015, 6:07 am
$

First, let me state that I have no problem forwarding mail to MOST external contacts by simply setting up a "Mail Contact" via ECP. Further, it appears that 100% of mail from internal addresses goes through properly to all external contacts. Where I run into problems is that for some mail originating at external sites, some users' ISPs reject the forwarded mail as spam. This happens often enough that I suspect I have not set up everything properly.

I don't have a problem forwarding to gmail.com, outlook.com, or other big e-mail systems. The e-mail may end up in the recipient's junk mail, but at least it gets through and users can add us to their Safe lists to prevent this problem. But with several ISPs, the mail is blocked completely. Nothing reaches the contact at all, nor does the sender get a message back with any kind of support information (because these are forwarded messages, even if there were a reply, it wouldn't come to us). Example ISPs that reject forward messages at the SMTP level include EarthLink and FairPoint.

We are not on any DNS blacklists. Whatever the reason for the blocking, we assume (don't know for sure) that they are exceeding some spam score threshold and triggering the block. Supporting this hypothesis: test mail I send from my own gmail or yahoo accounts to their address on our Exchange Server does reach some of the problematic external contacts, but automated mail from other sources (like invites to complete registration for third party tools, like a RingCentral phone account) never reach these users.

These are completely legitimate individual e-mails that are being rejected outright by the external recipients' ISPs.

A few questions on this problem:

  1. Everything I see on the Internet says to create a user account and a mail contact, and then forward the user's mail to the mail contact. This has always seemed like a waste of time for me -- I just create a mail contact John Doe in ECP, with an internal address of John.Doe@MyCompany.com, and then set it to forward to John's external SMTP gmail account atjdoe@gmail.com. Am I missing something? Is there any benefit to also creating the user account? If all mail is only going to the person's external mail address, is there any problem with only creating the mail Contact as I have been doing? Could this be related to the spam blocking problem with the forwards?
  2. Are there any rDNS or other settings I should make either on the Exchange server, our on-site DNS server, or with our external DNS to make our mail appear more legitimate and less likely to be flagged as spam? Maybe we've failed to follow some best practices on setting everything up, which increases our spam score, explaining both the rejections and the frequent junk mail filing.
  3. Any suggestions on how to better research this to find out WHY the messages are being blocked? The ISPs don't respond to questions on this. Their support personnel are unaware and claim they don't block e-mail. But obviously they do.

Thanks for any help or suggestions to troubleshoot and work toward a resolution to this problem,
Colin

Delivery Report for multiple recipients.

Hello all,

An issue i am facing with a brand new exchange 2013 install with CU8 is as follows.

I create an email message and address it to multiple recipients both internal and external, i then send the message.

When i go to Delivery reports and view it, the internal recipients all show delivered. External recipient shows as Pending HOWEVER it was SUCCESSFULLY delivered to the external address.  The report does not seem to update and show that it was delivered though. This has happened on every email sent that contains both internal and external addresses.  If an email is sent with ONLY external addresses in the TO field, then it shows as delivered, this issue only occurs when there are both internal and external addresses.

Here is a screenshot of the report, the external gmail address used in the test was mine, and i don't care if anyone knows it.

Exchange 2007/2013 Migration / Intra-Organization SMTP Send Connector

Hi.

We are currently migrating from Exchange 2007 to Exchange 2013. We have Exchange servers across 3 AD Site (A, B &C). Right now, all our users are on Exchange 2007 except 2-3 test users. Exchange 2013 was installed in site A without any issue. At that moment, mail flow between users from site A to site B keep using Exchange 2007 hub servers in both directions; Exchange 2013 Transport Servers in site A were not used at all.

When we installed Exchange 2013 in site B, mailbox flow between Exchange 2007 users from site A to Exchange 2007 users in site B start using site B Exchange 2013 Transport servers. Why?

Right now, when site A users are sending email to site B, it’s using site B Exchange 2013 Transport Servers (Site A 2007 Mailbox Server, Site A 2007 Hub Server, Site B Exchange 2013 Transport Server, Site B 2007 Hub Server, Site b 2007 Mailbox Server). When site B users are sending email to site A, it’s keep using Exchange 2007 hub. (Site B 2007 Mailbox Server, Site B 2007 Hub, Site A 2007 Hub, Mailbox, Site A 2007 Mailbox Server).

Can someone explain why Exchange 2013 transport services are only used in site B and not A? Any documentation I can read that explain the result?

Thank you.

Scan to Mail in Junk Folder

Hi,

I'm a rookie with Exchange so go slow.

I setup a printer to scan to mail. But all the scans are going into the user's junk folder.

Can't add the sender to the safe list either because we get a "The e-mail address for this sender is internal to your organization and cannot be added to the list."

I've added the internal address to the Safe Sender list in Outlook manually (under Junk E-mail Options), but it still lands in the junk folder.

It's doing this on 6x PCs, all running Windows 7/XP with Outlook 2010.

Any ideas?

Thanks!

Sending mail from new domain through 365 SPAM filter gives SPF error

May 19, 2015, 7:43 am

Setting up an internal relay from one exchange forest to another. E-mail is flowing fine from a to b and going to the correct mailbox. The problem lies in sending from the mailbox in domain b with domain a address on it. Domain B uses Office 365 SPAM filter and when a message is sent out from domain A from Domain B it blocks it. We added domain A to the domain list on 365 and it seemed to fix it. Then after a few hours anyone sending to domain A from domain B were getting bounce backs (error below) : I'm guessing it is as simple as not setting the SPF record correctly to allow mail from domain a to be allowed to originate from domain b? Once I migrate all users from Domain a to b I will redirect the MX record to point to office 365 but I want to keep it where it is for now. Anyone have any experience with this?

I added a rule to block email with the word Cialis in it.

However the domain I send email to is is.co.za and the rule blocks it. How daft is this. The rule should look for the whole word not parts of it

Is there a way to make it look at the whole word, or am I going to be inundated with adverts for Cialis?

TIA

Add a dynamic group to Message Delivery Restrictions

Hello,

We can add a dynamic distribution group to "Message Delivery Restrictions" in Exchange 2010 but what i worry about that is performance. Is that cause a problem in a big organization (more than 1 million daily mail traffic)?

It's a good solution for a group to restrict receiving mails from everywhere. but it may cause performance problem if we generalize for more mail groups or mailboxes. Because when i add a dynamic group, mails delay more than normally.

Thanks in advance.

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?

Hi everyone,

In my Org. I have Exchange 2010 and 2013 servers.

I have created two transport rule:

  • Block spesific attachments extensions (on Exchange 2010 - for mailboxes located on that server).

This rule also is applied on 2013 Mailbox servers.

Now I'm getting some requests from my users - the rule is applied where it should not.

Could you please explain, how can I track, WHY the rule is applied? It rejects the messages where no attachments at all..

Exchange 2013 Attachment Size Issue

Hi everybody,

I'm having some trouble with an Exchange 2013 server.

The users are not able to receive messages with a size bigger than 10MB, i tried with serveral attachments.

I already did te following:

Changed the maximum receive size through the ECP to 60MB (on the default frontend Exchange), and restarted te transport service.

Set the receive size through PowerShell with the following command.

set-transportconfig -maxreceivesize 35MB

when i check the receive size properties, it accepts 35MB messages. (get-transportconfig -property maxreceivesize)

Also restarted serveral Exchange transport services.

Checked the router if there are any special firewall rules, but there are none.

When I send an email with an attachment (PDF about 4 meg), it receives like it should.

Once I send a same email but with an 11meg PDF file, it is not delivered.

When sending this e-mail and attechment, i checked the box to notify me when the message has been deliverd.

I don't get any response, no NDR, nothing...

Tried e-mail tracking but there is no trace of my message.

Am I missing anything?

Kind regards,

Tim
