Multiple Smart Hosts within a send connector issue

Our organization has 2 smart hosts that our hub transport can use for outbound e-mail.  We have created a send-connector that lists both IPs.  As expected, if one is unavailable it just uses the other.  What I have noticed is that as long
as both Smart hosts are online Exchange uses a round-robin format with the 2 smart hosts for anything going out that send connector.  What I am looking for is to somehow disable the round-robin feature.  I would like all mail going out this send
connector to always use just 1 of the 2 smart hosts and ONLY use the second if the first is unavailable for some reason.  Is this possible?

Not really possible with the native Exchange capabilities, no.
If you have a load balancer, you might be able to leverage that and have Exchange send to single namespace that is handled by the balancer.

  • Send connector with smart host redirection for particular domain

    Hello,
    We have quite big environment with Ex2007 CCR cluster with 2x CAS/HUB and 2x Edge servers with few accepted authoritative domains for several countries. Currently all mails from these are routed through one send connector.
    We're moving to a different mail filtering service and I wanted to setup one of our domains to send through the new service to get it all setup and working correctly before moving the other domains over to it.
    So i have configured dedicated new custom send connector ( in accordance with techent article: http://technet.microsoft.com/en-us/library/aa998814%28v=exchg.80%29.aspx) for one of our domains let's say contoso.com with priority 1, and in next step i have
    entered smart host ip's and at the end source servers (2x edge servers).
    I have spotted that mail would still not send through my new send connector for those with email addresses with that domain. I turned on verbose logging but still all emails are not going through new connector. I checked that changes were replicated succesfully
    on Edge servers and I restarted  on Cas/Hub machines "EdgeSync" service but still no luck.
    Please help me did I forgot to check/change something?

    Let me be sure I understand how you have your new send connector configured, so I don't give you the wrong information.  You said you configured the new send connector with the contoso.com email domain.  From how you said it, though ("one of
    our domains"), it appears that email domain is one of your internal email domains.  If this is the case, this is why this send connector isn't being used - the send connector will send only to those email domains listed in the address
    space tab.  If I am right, it will never send to any external recipients with an contoso.com email address - those mailboxes are internal.  If you have an external SMTP domain in that list (such as hotmail.com), you should see messages sent to recipients
    on that system through this connector.
    If I am not right in how I read your posting, let me know so we can figure out how to get your send connector working properly.

  • Exchange 2013 will not send out email using MX records, but will via smart host.

    When I use a smart host my email goes out fine, but when I use MX look-up it does not.  
    Inbound mail works when I use Telnet to test it. 
    Could this be because I'm testing the server from our office that the FQDN on the Exchange Server will not resolve back to the IP address I'm testing from? 

    Yes almost certainly.
    If when the server does the MX lookup for the destination address it resolves to your external IP address then it's quite likely that it won't be able to send. A lot of firewalls can't handle having a connection made from the internal network for an external
    IP address that it controls, and won't simply pass the connection back to the internal network. When using the smart host though, the destination is external so the message can reach it and then when the smart host tries to deliver the message to your external
    IP it's coming from an external source so it works.
    Tricky one to explain but I hope that makes sense.

  • How to create send connectors for multiple sites in the same domain?

    Current Scenario:
    We have 2 offices, 1 in London and 1 in India. Both are in the same domain and are connected via VPN. Both have their own separate Exchange 2003 server. Each location sends out their mail via the Default SMTP Virtual Server on their exchange server through
    their local ISP. There are no Send connectors created currently.
    We have now installed an additional Exchange 2010 server with Hub, CAS and Mailbox roles at the London site. Internal mail flow between the sites seems to be working fine.
    I believe the Exchange 2010 needs a Send connector to send out mail to the internet. However as soon as we create a Send connector on Exchange 2010, mail from the older 2003 servers at both sites start to flow out from the exchange 2010 server. This is not
    optimal for our India site since their outgoing mail now has to flow via the VPN to London and out via the new server.
    How can we configure it so that each server sends outgoing mail independently?
    Thanks

    Hi,
    In India site, you can create a SMTP connector which point to the local ISP.
    Thanks.

  • How to send email to a SMTP server over a secure channel using STARTTLS setting of a send connector (Exchange and SMTP server are in the same domain)

    I’m trying to send email using exchange send connector STARTTLS setting to the SMTP server. I have read multiple documents on configuring TLS for send connector, but they talks about outbound connections to internet facing servers. My Exchange 2013 and SMTP
    server is in the same domain (let’s say A.com) and I’m creating dummy domains on my SMTP server (e.g.
    [email protected],
    [email protected] ) and their respective send connectors on the exchange server end. In the smart host section added the IP address of the SMTP server and in the scoping section added the SMTP domain address (e.g. dummy1.local ). In the FQDN field, added
    the FQDN of the exchange server 2013 which certificate is enabled with SMTP service.
    Could you tell me a step by step procedure, where I’m going wrong or any extra settings needs to added?
    Presently, it is giving me an error that 530 5.5.1 TLS encrypted connection is required.
    Note: I’ve created the Microsoft CA certificates for the SMTP and exchange servers and imported them in the personal certificate container. In which, the exchange certificate is created with FQDN name of the server and enabled for the SMTP service.
    I’m using OPENSSL certificate for making the SMTP server TLS enabled. (let me know, if I need to import the OPENSSL certificate anywhere on the exchange end)?
    Thanks!

    -IgnoreSTARTTLS is set to false on the send connector properties.
    I'm trying to established a HTTP over TLS connection. I'm not using mutual TLS between these two server.

  • Exchange 2007 send connector does nor respect Maximum message size (sometimes...)

    Hi to all
    We have 9 email server, 5 Mailboxes, 2 CAS and 2 HT, We began to have problems to send and receive from internet; so I checked the queues and I discovered that some users are sending messages with a size greater than 16 MB, althought internally can send
    until 40MB, if they send externally, only until 16MB.
    I revised all the configuration:
    Organization Configuration/Hub Transport/Global Settings/ Maximum send size (KB):40960
    Server Configuration/Hub Transport/HT01/Receive Connectors/Default HT01/Maximum message size(KB): 40960 (only this server can send outside, the other server is in spare)
    Organization Configuration/Hub Transport/Send Connector/SendMailOuside/Maximum message size(KB) 16386
    We send by an Smart host that is used only by the HT01 to a Symantec server.
    With this, we have this situations:
    In the queue, I see some users are sending emails with a size more than 16MB outside the organization, I revised their configuration and the "maximun send size" is clear the checkbox (just like my account), the weir is if I try to send an email
    with a size more than 16MB, I got the message: "#550 5.3.4 ROUTING.SizeLimit; message size exceeds fixed maximum size for route ##", this is not sense because their account configuration is the same like mine, so the Exchange must not let
    them to put the email in the queue...
    If between internal users try to send an email with size more than 16MB, this is allowed and it's send without any problem
    So I don't know where is the misconfiguration, is permited to send mails with size less than 40MB internally, but externally only until to 16MB, but I din't know why the Exchange system let some users to send (or at least put in the queue) this kind of messages,
    my account is in the same DB like the other users...
    I hope to be clear in the description of the situation, maybe a patch or some thing, the HT server has the January patch and in april will be applied the last patchs.
    Doc MX

    Hi DocMX,
    Thank you for your question.
    We could run the following command:
    Get-TransportConfig | FL max*size
    Then, we could check the send connector by the following command:
    Get-SendConnector | FL Identity,MaxMessageSize
    We could run the following command to check an individual user maximum size.
    Get-Mailbox <username> | FL Name,Max*size
    In my solution, we could rebuild the user profile that those users could send emails more than 16MB to check if the issue persist.
    We could also restart the service of “Microsoft Exchange Transport”.
    If there are any questions regarding this issue, please be free to let me know. 
    Best Regard,
    Jim

  • Exchange 2013 SP1 cu8 - mssing cmdlet - Get-SendConnector command missing, cannot change smart host port

    Hi Everybody,
    For some reason my Exchange 2013 SP1 cu8 are missing a bunch of cmdlets.
    When i run the exchange powershell and get all the cmdlet command - i noticed all the send and receive connectors are missing.
    This all started when i needed to change the smart host port for a client because their internet provider was blocking port 25.
    So i did the traditional cmdlet
    Get-SendConnector
    Set-SendConnector -Indentity "connector name" -Port 551
    Both commands i get "The term Get-SendConnector is not recognized as the name of a cmdlet, function, etc"
    When i type Get-ExCommand
    Any reference to SendConnector and ReceiveConnector are not on the list.
    Am I missing somethings?  This is a classic example why GUI and cmdlet functions should both be available and not just on cmdlets.
    I went on other Exchange 2013 SP1 cu7 servers to see, and they all have the Send and Receive connectors in the cmdlets.
    The only difference with this particular setup, is that this is the first Exchange 2013 on-premise installation with Windows 2012 r2 Small Business Essentials.  However, i very much doubt the on-premise installation add-on to SBS would cause any issues
    to missing cmdlets.
    I searched all over the internet and found nothing.
    Now my biggest fear is to re-install Exchange and import the mailboxes manually.
    Any help is greatly appreciated.

  • Configure send connector for exchange online protection

    Hello Forum members,
    I am trying to configure send and receive connectors for Exchange 2010 to route
    on-premises mailboxes to Exchange OnLine Protection.  The "help" info MS provides
    is for Ex 2013 - and the EAC GUI and config does not lend a close fit to using the 2010
    Exch Management Console.  How can I configure connectors to properly connect to the Exchange Online Protection?
    I have seen where the ip addresses are posted, etc.  I am unclear how to configure the properties on the SBS 2011/EX 2010 server.
    Any tips will help,
    Thanks,
    Eric H.

    Hello Wesleyhe,
    You cannot use AD anything with EOP - if you mean exchange on-line protection.
    you have to set a smart host on the SBS server to connect to EOP, you may need to add the EOP server ips to your network config
    on the SBS server.  the smart host line (for the send connector on SBS server) is something like: yourdomainname-com.mail.protection.outlook.com.
    Then you need to configure the outside ip for your SBS server access in the EOP admin area.
    Hope this helps.

  • Exchange 2007 Smarthost send connector backing up

    I have seen some similar posts to this but none have had any good answers.
    We route all outbound mail through an Barracuda spam/virus appliance. We are a busy college campus with roughly 2k staff banging away at our mail gateways with mass mailings to our students, homework assignments, class schedules, blah blah blah..
    At no time is our outbound mail queue empty. The trouble is, is that at any given time the most "Active" delivery status messages I see in queue viewer is 6 messages. Whether there are 30 or 5000 messages stuck in there it never try's to send
    more than 6 at a time.
    Sometimes the queue viewer shows no "Active" connections just all "Ready's". I never see the status change to "Retry" or anything else other than "Ready" or "Active".
    We often have delivery delays of 3 or 4 hours when mass mailing messages that do not exceed more than 10 to 20k.
    Here is what we've tried so far:
    In Powershell use: get-transportserver | fl   (to view these)
    and use:  set-transportserver -ConfiguratorName  (to change the values)
    updated MaxConcurrentMailboxDeliveries to 50
    updated MaxConcurrentMailboxSubmissions to 50
    updated PickupDirectoryMaxMessagesPerMinute to 200
    MaxConnectionRatePerMinute 1200
    MaxOutboundConnections 1000
    MaxPerDomainOutboundConnections 1000
    "...MaxMessageAttachSize" 100MB (For testing only)
    use: get-sendconnector | fl    to verify the value of "MaxMessageSize". Ours is set to unlimited.
    use: get-transportconfig   to check all the "Max" settings in there particularly the MaxDumpsterSizePerStorageGroup setting. Ours is 125MB.
    Protocol logging is set to Verbose on the send connector. There are no error messages in the send or connectivity logs. The "Microsoft MailFlow Troubleshooter" is a joke.
    We have no throttling turned on at the Barracuda level, so says their tech support. I of course have no way of verifying this as I do not have access to it.
    I guess my question is. Does anyone know how or where we can increase the number of "Active" messages in the queue to more than 6 messages?

    You're sending all mail to a single smart host? I'd be looking at that
    machine's configuration.
    >Sometimes the queue viewer shows no "Active" connections just all "Ready's". I never see the status change to "Retry" or anything else other than "Ready" or "Active".
    You have only one queue, for the smart host, right? Is there a "Last
    error" value for it?
    Are there any "back-pressure" events in the server's application event
    log?

    The barracuda has DOS protection. I *think* the default is to limit
    the number of "parrallel connections" to 5, but that may be different
    on different models. There are probably other "rate limiting"
    settings, too.

  • Smart Hosts & DNS records

    Hi All.
    I hope someone could assist me as I have been struggling with mail flow issues for a long time.
    We have our own in house exchange server and internal mail as well as incoming mail is 100 %.
    We have always used our ISP smart host to send email and started getting email flow issues a couple of months ago.
    I then switched over to sending email via DNS. I setup the correct DNS records eg Reverse Lookup record and SPF records as i thought this might be an issue. I have also cleared our domain off one or 2 blacklists. (We had a user account compramised and spammers
    were using that account to send email)
    This is now all cleared up and general outbound email flow is going great, but once again we are now experiencing issues with all clients filtering with Mail Marshall.. Message as below:
    Your message did not reach some or all of the intended recipients.
    Subject:    Email
    Sent: 2014/09/16 09:02 AM
    The following recipient(s) cannot be reached:
    [email protected] on 2014/09/16 09:02 AM
    There was a SMTP communication problem with the recipient's email server. 
    Please contact your system administrator.
    <example.example.org.za #5.5.0 smtp;550 Message refused by MailMarshal SpamProfiler>
    Has anyone got any advice on what I can do. The failed report doesnt give much help. I have also sent an email with just text to see if maybe its the email signature but still
    no luck.
    I'm thinking of switching back to the ISP as a smart host but I'm not sure if the SPF and reverse DNS records would cause an issue now.
    Would our clients not look at the reverse and SPF record and see that the IP (ISP Smarthost) doesn't match our IP lised in the public DNS ?
    Much Appreciated.
    Shaun

    Hi.
    I contacted the support for Mail Marshal and they got back to me and sorted out the issue. It seems fine for now.. They were really helpful I must say.
    The response from them for anyone else with the same issue perhaps.
    Regards,
    Shaun
    Hi Shaun,
    It is not a blacklist exactly. SpamProfiler is run on a fingerprint (or pattern) basis. It scans the content of the email message and then acts accordingly to the fingerprints it finds. Due to emails containing your
    email domain being submitted as spam and/or mails you sent hitting honey pots, the fingerprint of your domain was flagged as a spam URL. Hence the recommendation to audit your mailing lists. So it was the pattern of the domain that was in the system. Unfortunately
    that is not something you can check on MX Toolbox, as Cloudmark (the company that provides the fingerprints for SpamProfiler) does not make their fingerprints publically available

  • Mail Delay from Exchange to Smart Host

    I have this POC setup.  I have 2 smart host appliances sending and receiving.  Exchange 2010 sp3.
    Mail flow in/out working fine.  I have one send connector with both the hosts in it with IPs.
    I notice when ever I send an email from Outlook it take about 15-40 seconds of delay between exchange and Hosts.  The delay seems to be on exchange side sending to the host.
    Any thoughts?  I will do some more tests ...
    Tnx

    If I put one host in the connector then there is NO delay at all. 
    It appears that when there are 2 hosts in the One connector exchange takes its time to figure out that to which host should it send hence causung they delay ranging from 20 to 45 secs.

  • In Pages (5.5.1) can I create multiple Paragraph Styles within one paragraph?

    In Pages (5.5.1) can I create multiple Paragraph Styles within one paragraph. 
    I need to make a table of contents for my Mater's Thesis and want to use the automatic table of contents feature.  I want the first sentence of a paragraph to have a different paragraph setting than the rest of the paragraph.  Is this possible?
    Thanks!

    Nice of you to be doing this for your Mother's Thesis.
    There are several issues here:
    1. A Paragraph Style is what it says, the style for the paragraph
    2. You can format text within a paragraph by applying a Character Style
    3. Pages 5.5.1 lets you apply formatting to overall text for the T.O.C. but not parts of it and you can not retain that formatting as a Paragraph style
    So in answer to your question, no.
    You will need to create the T.O.C. manually and unfortunately as Pages 5.5.1 can't create bookmarks (just one of over 100 missing features) you will be unable to link the T.O.C. to the referred pages in the list.

  • Multiple Relay Host question

    In the GWIA settings under SMTP/MIME, the "Relay Host for outbound messages" we have the address for a Cisco Ironport c170 that filters our messages.
    We want to add another Ironport for failover. If I add a second IP, can this be prioritized so the 2nd unit will only be used if the 1st is down?
    What logic will/might be used when a second relay host is used?
    Am I approaching this right or should I plan to let it send from either relay host?
    Thank you for any help you can offer.

    I Like that answer!!!
    On the Public side we are going to have different priorities on the MX Records.
    I would prefer that One Ironport get all the messages, but realize they both most likely will.
    We Quarantine all messages with attachments and manually release them "if" the recipient calls us to let us know they were expecting the message or know he sender.
    So I assume we will have to check both Ironports to see which did the quarantine.
    We will be using the Ironport Centralized Management to keep the two Ironport configurations the same.
    If you have any recommendations or tips, Please share.
    Thank You

    We are also using a clustered IronPort solution. We have both IP's

    the first IP is always used until it fails.

  • What are the correct Send Connectors settings in Exchange 2013

    Hi
    I'm new to exchange, successfully setup a lab with 2 cashub roles and 2 mailbox roles. I am trying to set the send connectors settings, because I've not been able to send nor receive external email via owa. Since I'm separating the exchange roles, my mailbox
    servers only use internal IP settings and cannot resolve external DNS. I'm thinking I need to tick, proxy through CAS for it to work? any suggestions?

    Hi 
    Can you please let us know what version of Exchange that you are using 
    "I'm new to exchange, successfully setup a lab with 2 cashub roles and 2 mailbox roles"
    - Because Exchange 2013 does not hold hub role.
    " I am trying to set the send connectors settings, because I've not been able to send
    nor receive external email via owa."
    It would be great if you could answer few questions so that people can help you out here
    Are you able to send emails internally without any issues with Outlook ? If not can you paste the errors.
    What error you are getting while trying to send emails through owa . Can you paste the errors.
