Re: Inbound email problem

It all sounds a bit strange to me.
Your MX record mail.stpaulsumctucson.net resolves to 65.101.185.33 which you
say is your static IP. Is this the IP of the actiontec modem? And you are
totally sure that port 25 is forwarded to the SBS external nic?

How do you use RWW? Do you have another DNS host such as
rww.stpaulsumctucson.net/remote ? If so, what IP address does it resolve
to?

stpaulsumctucson.net resolves to 66.113.136.225 Is this an external web
server?

I think what you mean about the CEICW and alternate IP addresses is for the
internal DNS server's forwarder IP's. They would have nothing to do with
inbound email.

I would say that either 65.101.185.33 is not the address of your modem, or
the modem is not properly forwarding traffic.

DNS checks out OK.

Could it be that Qwest is blocking port 25 traffic? Probably not if
outbound mail works.

As a test, change the port that Exchange smtp listens on (and make sure
you
port forward the new setting to your sbs external nic)

look at: http://support.microsoft.com/kb/274842

When is the last time you ran the CEICW? Maybe you should try that first.

Thanks,

What is the name of your company domain and what is the public ip
address?
It sounds like they are not matching in DNS.
Can you telnet into your exchange server?
Do you have exchange server antispam or connection filtering enabled?

I am running SBS 2003 Standard on a Dell PowerEdge 1800 with 2 NICs.
External NIC is connected to Qwest provided Actiontec GT701WG modem/
router. I can RWW, I can send email, I can receive pop mail for our
qwestoffice email addresses. I cannot receive inbound email if it is
sent to our company domain name address. I have a public static IP
with MX and A records setup. When I used dnsstuff to obtain a dns
report, the report indicated fail at connect to mail servers (Error: I
could not complete a connection to any of your mailservers) When I
did an email test I received the error "The mailserver terminated the
connection before the transaction was complete (state1). This is not
RFC compliant, and therefore either due to an error, or it may be the
result of a non-RFC-compliant mailserver or non-RFC-complaint anti-
spam program.

Any insight on what is creating my problem would be greatly
appreciated.- Hide quoted text -

Qwest checked it out and verified that Port 25 had no filtering
assigned. I ran the CEICW yesterday after forwarding ports on the
Actiontec. I might tell you I started having these problems after
Qwest moved our email to their new servers (Qwestoffice) and told me I
needed to change my DNS server at my registrar. The funny thing is,
if I don't use the old primary DSN IP as one of the entries in CEICW
(using it as the alternate) I can't access a lot of internet sites.
Internet access is still at Qwest.net. Don't know if this is any help
or just muddies the water. I'll rerun CEICW tomorrow when I get to
work. In the mean time, I'll read the KB you sent the link for.
