  • Hi,

    I'm trying to configure my exchange server for now more than one week, my users don't have external mails working and I'm out of ideas!!

    I have the error "451 4.4.0 Primary target IP address responded with: "421 4.4.2 Connection dropped." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternates."

    I looked in the smtpsendconnector, and the error says :"Failed to connect. Error Code: 10060, Error Message: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 189.176.111.38:26"

    I tried a telnet on port 26 of 189.176.111.38 and it doesn't work from the server. But it does work fine from a computer on another network.

    Also, I tried on the server a telnet to another mail server on port 26, and it worked just fine. I also tried the telnet to 189.176.111.38 from another computer on the network, but it doesn't work neither.

    So I do miss something, but I can't figured out what!! Outbound traffic on port 26 is OK. Inbound traffic to the exchange server on port 26 is OK. But traffic from the server to the server through internet is NOK.

    Obviously, a telnet on the server's own local interface is OK.

    I guess this is the problem of sending and receiving external emails. It used to work fine for several month, and then it just stopped to work, and worked again for few hours this week (I thaught the problem was solved) an then stopped again.

    Do you have any idea about what could be causing the problem?

    Thank you.

     

    Configuration :

    SBS2008, Exchange 2007

  • We have an hardware firewall, but I guess if it was the firewall, it would block any inbound traffic, but I'm able to connect the server on telnet 26 from another network. It could be outbound traffic, but also I guess I wouldn't be able to telnet from the server to another external mail server on port 26.

    Is that correct?


    I precise that all inbound traffic on port 26 is configured to be redirected to the server.

  • Port 26?  I hope that's a typo.

    The firewall may allow connections from some addresses but not others.  I'd check the FW logs for block events and see if anything corresponds to your failed connection attempts.

  • Hi,

    Sorry for the response delay, but I was checking my firewall settings and logs but I can't find anything!

    It's really strange because I have 2 interfaces for receiving mails > 1.5 and 2.5

    From an external computer, yesterday, I was able to telnet both on port 26, but not from the server itself.

    Now today, even from the external computer, I'm only able to telnet 2.5. And still none of them from the SBS server.

    Here are the logs

    Seems like it can connect, then it cannot...

    I'm still checking the firewall but nothing is filtering adresses. I only have a rule on the firewall > Send Inbound traffic to the SBS server. (Each firewall or each interface has the same rule).

    Any more ideas?

  • 189.176.121.56 and 189.176.111.38 are my two internet interfaces.

    nautilius.com.mx is my smarthost.

    My ISP blocks ports 25, and my host is using port 26.

    But it should be working on port 26

    Port 26 is not blocked as I can telnet my smarthost on port 26 from my SBS server with no problem.

  • According to the firewall logs, the smarthost appears to be accepting connectoins from the 121.56 connector, but not from the 111.38 connector.

    It looks like the problem may be at that smart host.

    These were the sendConnector logs, not from the firewall. And the two IP address are my internet interfaces, not the smarthost.

    Yes. Absolutely! And that's the crazy thing! I can telnet my smarthost from the SBS server, I was able (not any more) to telnet 189.176.111.38:26 from an external source, but I'm not able to telnet the server from the server (throught the internet, locally it works fine).

    NO. My SBS server has 2 local adresses (actually 4, but whatever...), wich are both behind a firewall. One firewall is directly connected to the internet via a modem (189.176.121.56), the other firewall goes to another modem/router to use the internet (189.176.111.38). This ultimate modem/router is configured to have the WAN interface of the firewall in the DMZ so all traffic is sent to the firewall.

  • When you telenet to the smarthost from your sbs server, did you specify which of it's IP addresses to use for the connection?  If you didn't then the smarthost may be refusing connections from 189.176.111.38, and your telenet test was actually testing connection from one of the other addresses.

  • Here comes some news ! I'm now able to receive mails !! I still can't send, all the mails are stucked in the queue, but receiving is a first step.

    I still don't understand everything but well... On my firewall's logs of the 111.38 interface (which now has change, it's not a fixed IP - we can call it I1), I saw a lot of inbound traffic on port 25 which was, as required, redirected to my SBS Server. But so far I couldn't receive any mail. This traffic seemed to come from hotmail. I tried to telnet hotmail on port 25, but no response because, my ISP should block port 25. That's why on the other interface 121.26 (we can call it I2), I had only forwarded port 26 and 587, but not 25. But as I saw this traffic, I tried to forward port 25 from I2 to the server, and it worked !!

    So I still don't understand why it doesn't work from I1, wich I would like to use as backup mail interface. My receive connector is configured to listen on any interface, on port 25, 26 and 587. But well.... at least users can now receive mails.

    About sending, I still have the problem. I tried to disable I1 interface directly on the server trying to force it pass through I2, but no results.

  • You cannot use a dialup/dhcp connection to receive email.

    You need a fixed address, and MX records to match. If that address changes, it won't match your MX records any more.

    yes, obviouly, and that's why I'm using dyndns name resolution, and I've set my dyndns string in the MX record. This part seems to be working as I can now receive emails.

    Now, here comes the new logs from the send connector (189.176.142.84 is my new I1 IP) :

    There's error on I1, but I don't understand why emails are not sent from I2 !

  •  think you could probably save yourself a lot of time if you would contact whoever controls that smarthost and have them check their logs. 

    They are in a much better position to determine why those connections are being refused than anyone on this forum.

    Actually, that's what I did from the begining, but they didn't really help me. Worst, they gave me some advices on my MX Record configuration wich were finally not good.

    Something strange I get on my firewall logs, is

    2011 Sep  6 20:19:05 [Admon] [kernel] WAN2LAN[ACCEPT]  IN=LAN  OUT=LAN SRC=192.168.2.5 DST=192.168.2.5 PROTO=TCP SPT=35027 DPT=26 
    2011 Sep  6 20:19:05 [Admon] [kernel] WAN2LAN[ACCEPT]  IN=LAN  OUT=LAN SRC=192.168.2.5 DST=192.168.2.5 PROTO=TCP SPT=35028 DPT=26 
    2011 Sep  6 20:19:05 [Admon] [kernel]  LAN2WAN[ACCEPT] 
    
    It seems like mails are looping ! SRC = DST
    I don't understand if it could come from the firewall or the exchange configuration. I think more about the exchange server because I tried to remove any outbound firewall rules (which are basically QoS rules), and it doesn't work better.

  • Hi,

    Here is my conversation with the web host :

    Me: [12:27:11 PM] We are having troubles with external emails communications since almost 2 weeks. We are now able to receive mails, but not to send. We are using XXXXXXXX as our smarthost. Could you tell me if you can see any email traffic on port 26 from our server (189.176.121.56) on subdomain nautilius.com.mx ? Thank you.
    Smarthost: [12:28:35 PM] no I am not showing incoming or outgoing mail for that domain
    Me: [12:31:49 PM] You should see incoming log... I just sent a message from an external account to our server, through the MX Record
    Smarthost: [12:33:01 PM] nope I am not showing anything with us
    [12:33:05 PM] the MX is set to MX Entries 10 cxxxxxxx.dxxxxxxx.org.
    20 nxxxxxx.mxxxxxxxx.cxxx.
    Me: [12:33:35 PM] yes and it worked correctly.
    [12:33:57 PM] but the problem comes from the other way
    [12:34:39 PM] but I guess if you can't see incoming traffic, you won't see outgoing traffic neither...
    Smarthost: [12:34:54 PM] yes anything going to the domain for mail is not with us
    Me: [12:35:39 PM] so you don't have any logs about MX traffic?
    Smarthost: [12:36:04 PM] no we do not log anything that does NOT hit our server
    [12:36:10 PM] you will need to check with the current mail host for those
    Me: [12:37:55 PM] that's what I'm trying to do for almost 2 weeks but mails do not go out and I wanted to know if there was anything to do with hostmonster or from our side
    Smarthost: [12:38:52 PM] not that I can see at this time
    Me: [12:41:47 PM] another question.... when I configure the smarthost in Exchange, I set as smarthost nautilius.com.mx with basic autentication using the user contact@nautilius.com.mx with its password I created in my CPanel. I do not set basic autentication with TLS. Is all these parameters correct?
    Smarthost: [12:43:28 PM] okay you would use the current mail host ignoring what you have done on our server since they are in control of the mail
    Me: [12:46:37 PM] I would like to send my emails from the exchange server, passing through my hosmonster subdomain nautilius.com.mx as smarthost
    Smarthost: [12:47:26 PM] okay I have NO idea on how to do that so you will need to work with the exchange server for how if that is even possible
    Me: [12:48:52 PM] alright, thank you.


    I don't know if I'm not explaining myself correctly but what I wanna do is pretty classic with Exchange server.

    I already pulled my hair out of my head and I'm now following with my nails !! ;-)

  • Problem solved manipulating MX Records.

    The web host was not playing fair.
