Help! External email not going out! |
|
|
We run Small Business Serve 2000. We do not use smarthosts.
No outbound email is going out. Some of our users began receiving Delivery
Status Notification (Delay)'s. All they say are:
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
Then it gives the email address it failed delivery to.
I can see that there are a ton of messages in the queue, under the Default
SMTP Virtual Server.
What should I look at for troubleshooting??
The only change I've made was last week - I installed SpamCatcher, I changed
the Exchange port to 6000 and then set the spamcatcher to point to the
servers IP on port 6000 but listen on 25. Outbound email worked for a few
days after that. Nevertheless I've stopped Spamcatcher today.
Many thanks, in advance!
Also, don't know if this is related, but we now cannot see our own website.
Yes, we have a forward lookup zone.

DNS.
Can you get out to the Internet and view web pages right now? How do you
have DNS set up?

More info:
When I go into Exchange System Manager, view the queue under the Default
SMTP Virtual Server, there's a ton of SmallBusiness SMTP connector entries,
for a ton of different destinatin domains. When I enumerate (list) messages
under some of the more popular domains, I see lots of messages coming from
postmaster@ our domain, as well as messages being sent by a user who hasn't
been here in six months. We've kept her account active so that we can have
her email forwarded to her replacement. She hasn't accessed her account,
and when I open up Outlook, no messages have been sent since March.
However, when I look in Mailbox Store, the last logon and last logoff times
for her mailbox were today, both at 12:33..
What am I missing???
Thanks!!

Make a .CMD file with this in it and use that.
@echo off
nslookup -querytype=MX %1 | find "="

Re: Help! External email not going out! |

Thank you so much for your help!
A) NIC is pointing to internal DNS server.
B) When I click Configure external DNS servers, that window is blank - there
are no external DNS servers for this virtual server.
Are these settings right?
I'm trying to figure out how to perform an NS lookup from my exchange
server. I went to a command prompt and typed NSLOOKUP. It told me my
server name and address, then gave me a prompt. When I type in domain
names, it gives me two sets of answers each time,
Server <my server's name>
Address <my address>;
Non-authoritative answer:
Name: <the domain name I typed>
Addresses: <ip address(es)>
Is this right?
Thanks!!

Yes, we can view web pages.
Not sure how to answer your question. We have two nics, internal &
external.
When I go to DNS, and to the properties of our server, it's listening
only on the internal NIC's IP. Forwarders are enabled, but I do not
recognize the IP addresses they're pointing to:
64.115.0.9 and 64.115.0.10
Looks related to our ISP - our server's external IP is 64.115.124.115
But when I asked our ISP today what their DNS is, he said 64.52.192.98
and 64.59.5.98. Not sure what to do with these.
Thank you!!!

Are External DNS Servers supposed to be configured for my SMTP Virtual
Server? I'm going to try that, not knowing what else to try. I've just
rebooted the server, just to see if that would have an effect. It did not.
I don't know if this is realted, but earlier last week, we got the following
NDR when we tried to email a person at our Italian subdomain (this had been
working fine previously)
John Doe on 10/28/2005 4:44 PM
A configuration error in the e-mail system caused the message to
bounce between two servers or to be forwarded between two recipients.
Contact your administrator.
<SAI.sa-intl.org #4.4.6>
When I searched the archives on this error message, one responder refers to
this:
http://support.microsoft.com/?id=316617
Would this apply to our situation? Isn't it dangerous to delete the SMTP
connector?
Many thanks in advance!!

This one is disturbing.
When I rebooted the server, after logging in, I received a message that
said: "Windows has finished installing new devices. Do you want to restart
now?" I said No.
Only new thing has been Spamcatcher, which shouldn't be a device. Nothing
looks amiss in Device Manager. Spybot and Symantec Antivirus are clear,
although they're not perfect.
Should I rerun Internet Connection Wizard?

You're duplicating what the Exchange SMTP server does when it tries to
deliver mail, namely connecting to port 25 on a mail server. If you can't
do it, neither can Exchange. The question now is why not, so how does the
machine connect to the internet? (Via ISA, another firewall, a DSL router,
etc)

Ah.
1) When I NSLOOKUP my personal ISP, inch.com, it does locate it, and it
shows me their IP address. However,
2) When, from a command prompt, I say telnet inch.com, it responds with
"Connecting to inch.com... <then it takes a minute, then says> Could not
open a connection to host on port 23: Connect failed. When I try telnet
inch.com 25, it replies with Could not open a connection to host on port 25:
Connect failed.
So DNS is working, but not telnet?
Thank you!

Back to basics:
1) Is DNS working properly? IE, can you locate MX records via NSLOOKUP?
2) If #1 is Yes: lookup somebody's MX record and telnet to it (ie telnet
somebodys.mail.com 25) and see if you get the SMTP banner.

We have a DSL router. Two NICs, external one goes to the router. Using
ISA. Using the internal NIC's IP as the DNS server. We certainly do have
internet access. How to find out why the SMTP server doesn't have internet
access?
On the Default SMTP Virtual Server's Properties, Access tab, Authentication
button, all options are checked as acceptable authentication methods.
The only change in this configuration (aside from me adding external DNS
servers in the Advanced Delivery section, about an hour ago) was what I did
for SpamCatcher last week. I changed the Exchange port from 25 to 6000, and
told SpamCatcher to point to the server's IP on 6000, and listen on 25. But
shouldn't that only be for incoming mail? How could that affect outgoing?
Also, that was done on Thursday, and we had two or three days of successful
emailing after that. Even so, I'm thinking of uninstalling SpamCatcher for
now, just to simplify, and returning the server's port to 25.
How else to troubleshoot SMTP connection problems??
Many thanks!!!

That would be to get a unix shell, which is entirely different.
Was I supposed to be able to learn that I should use telnet.inch.com by
doing nslookup? Maybe doesn't matter at this point, I cannot telnet to
them.
You're duplicating what the Exchange SMTP server does when it tries to
deliver mail, namely connecting to port 25 on a mail server. If you can't
do it, neither can Exchange. The question now is why not, so how does the
machine connect to the internet? (Via ISA, another firewall, a DSL router,
etc)
