kavinagpur -> Unable to receive mail from internet (29.Sep.2008 7:58:14 AM)

Dear all,

I have configured Exchange 2003 for SBS. I can send receive mail inside the intranet. Can send the mail to internet domain like yahoo and hotmail. But i am unable to receive mail from outside world.

My Domain is with godaddy.

When i do mx lookup from mxtoolbox.com it shows 0.0.0.0 as ip address.

I have pointed my server ip address from godaddy. Also created a mx record mail.mydomain.net

I can telnet into my exchange from outside.

Somebody please help.

Thanks in advance

Vikas

Vikas,

If the mxtoolbox.com says 0.0.0.0 then you should check your external DNS configuration. Here the mx records and ptr records should also be created.

When doing the test on the mxtoolbox.com it should give your external IP-address.




Exchange_Geek -> RE: Unable to receive mail from internet (29.Sep.2008 9:34:41 AM)

Vikas,

Firstly, how does your mail flow work ?

Do you have some configuration sort of Internet - ISP - {{{ Firewall - Exchange }}}

If its similar then your MX record REGISTERED at your ISP should be the external IP of your Firewall - which would NAT and forward emails (on port 25) to Exchange server.

Remember, you dont require MX to send emails - you can simply create a SMTP Connector and have the smart host as your ISP - thats it.

Please check the ip address and its location with your ISP for MX registered with them.



kavinagpur -> RE: Unable to receive mail from internet (30.Sep.2008 12:14:51 AM)

Thanks for your reply.

just to tell you few things.

My domain is with godaddy. I have created MX record as mail.mydomain.net and host A record pointing to my Public IP provided by the ISP. My domain is not registered with ISP. Its with godaddy.com.

Do i need to do some settings from my ISP optusnet.

I have configured smart host. I can able send email to internet addresses but cant receive reply.

Do i need to change name server at godaddy. By default it has two ns server.

Also when i send mail it to exchange from outside it comes with




[email=MAILER-DAEMON@yahoo.com]MAILER-DAEMON@yahoo.com[/email] failure notice Sorry, I couldn't find a mail exchanger or IP address. Received: from [61.17.93.11] by web53103.mail.re2.yahoo.com via HTTP; Mon, 29 Sep 2008 20:06:45 PDT

Hi,

The coinopsolutions.net does have an mx record which points to mail.coinopsolutions.net when you do a lookup for that it won't exist. So you will need te create an a record for this which points to your external IP.




kavinagpur -> RE: Unable to receive mail from internet (1.Oct.2008 1:31:38 AM)

This is the settings i have done in godaddy:

A (Host) 
Host                               Points To                TTL 
@                                  58.108.208.65       1 Hour  
mail.coinopsolutions.net  58.108.208.65    1 Hour   

 
MX (Mail Exchange)  

Priority               Host            Goes To                             TTL 
10                       @               mail.coinopsolutions.net      1 Hour    

might give you some idea

Vikas   



Exchange_Geek -> RE: Unable to receive mail from internet (1.Oct.2008 7:55:08 AM)

Your problem isn't definitely not with your MX being registered atl least that is what is evident by this test done below.

> coinopsolutions.net

Non-authoritative answer:
coinopsolutions.net     MX preference = 10, mail exchanger = mail.coinopsolution
s.net

coinopsolutions.net     nameserver = ns19.domaincontrol.com
coinopsolutions.net     nameserver = ns20.domaincontrol.com

However, a simple telnet test fails - check this.

C:\>telnet mail.coinopsolutions.net 25
Connecting To mail.coinopsolutions.net...Could not open connection to the host, on port 25: Connect failed

This makes me think whats wrong with this server not accepting connection over port 25 - please check firewall settings to allow connection over port 25 at your ISP end for your IP and your end ofcourse.



kavinagpur -> RE: Unable to receive mail from internet (1.Oct.2008 8:51:39 AM)

but the test runs fine when i use ip address instead the domain name. I guess it fine.

any suggestions.

Regards,

Vikas



Exchange_Geek -> RE: Unable to receive mail from internet (1.Oct.2008 9:33:44 AM)

Buddy, i am not sure but your mx server mail isn't showing good response.

Checkdns.net has this to say for your domain.

CheckDNS.NET tests mail-servers

CheckDNS.NET is testing coinopsolutions.net

Please ESCALATE this matter with godaddy guys - since we are already having two such exact same issue with different clients - both are advised to get issues sorted from GoDaddy guys.



kavinagpur -> RE: Unable to receive mail from internet (1.Oct.2008 10:12:19 AM)

Thanks for you effort Exchange_Geek.

Tell me one thing do i need to do any changes to name servers.

It was already there in the godaddy.

I dint changed it.

I am constantly insending mails to godaddy. but not getting any solutions. they are asking me to contactc the email hosting provider.

do i need to provide name servers(in godaddy) to whom my public IP belongs(my ISP)?

Regards,

Vikas




jveldh -> RE: Unable to receive mail from internet (1.Oct.2008 1:12:58 PM)

Hi,

Also mxtoolbox gives an error. It says your mx records points to 0.0.0.0

Also telnet to 25 to the IP doesn't work, is there a firewall in front of Exchange ?




Exchange_Geek -> RE: Unable to receive mail from internet (1.Oct.2008 2:22:30 PM)

Technically speaking your mails should be routed to your ISP and they should forward your mails to your Exchange server - you could contact them and ask them to send emails and check their configuration to see if they are clear on their part.

At the moment you are getting sandwiched between godaddy and ISP.

Get the clearance from your ISP - as to can they telnet and email you and check if the traffic is clear from their part - reason why i was suggesting for GoDaddy guys to help you since we are repeatedly getting such similar complains - so its best for GoDaddy guys to clear their doubts before approaching ISP people.



kavinagpur -> RE: Unable to receive mail from internet (2.Oct.2008 2:26:20 AM)

When i do nslookup from within my server it shows

Microsoft Windows [Version 5.2.3790]
(C) Copyright 1985-2003 Microsoft Corp.
C:\Documents and Settings\Administrator>nslookup
Default Server:  exchange.smallbusiness.local

Server:  exchange.smallbusiness.local
Address:  192.168.2.79
coinopsolutions.net     MX preference = 10, mail exchanger = mail.coinopsolution
s.net
>

I think it should also display external IP (my static IP)



jveldh -> RE: Unable to receive mail from internet (2.Oct.2008 12:50:36 PM)

Hi,

This is correct you need to do the same on a machine that looks in the external DNS. The info you've got back now is info from the internal DNS server.




kavinagpur -> RE: Unable to receive mail from internet (4.Oct.2008 6:11:08 AM)

my SMTPVS is stopped and doesnt starts when i click on start.

Event Viewer says:

SMTP service has been stopped.

please help



Exchange_Geek -> RE: Unable to receive mail from internet (4.Oct.2008 8:24:30 AM)

Rename VS1 folder - recreate the folder - try starting SMTP Service - you would find pickup / queue folders being recreated - give full control to Everyone on Pickup folder - check if SMTP Service remains started.

I believe its because of corruption within VS1 folder that causes this issue.



kavinagpur -> RE: Unable to receive mail from internet (7.Oct.2008 11:11:03 PM)

I reinstalled the Exchange 2003 and the smtp seems to be working fine.

But a new problem: i am unable to send mail to outside world(internet):

getting system administrator message;

Your message did not reach some or all of the intended recipients.
     Subject: RE: hello vikas
     Sent: 8/10/2008 10:43 AM
The following recipient(s) could not be reached:
     vikaspatra@yahoo.com on 8/10/2008 10:56 AM
           The e-mail address could not be found.  Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address.  Check the address and try again.
           <mail.coinopsolutions.net #5.1.8 smtp;553 5.1.8 <vikaspatra@yahoo.com>... Domain of sender address vikas@CoinOpSolutions.local does not exist>

I guess its something wrong in my settings.

Thanks in advance



kavinagpur -> RE: Unable to receive mail from internet (7.Oct.2008 11:36:15 PM)

Regards,

Vikas



lukebrynycz -> RE: Unable to receive mail from internet (6.Jan.2009 4:56:56 AM)

Change your MX record at GoDaddy to point at your external IP and not the DNS name.  This should get things going.  Remember to wait 24hours for the change to take effect and if still not working, ring them to confirm.
