Re: Port 25 Not Open, can't receive mail

Hi Dave, thanks again for the reply.

I'm not quite sure on which other logs I can check - The event logs just
show the SMTP services stop and start, from the many times I have run the
CEICW. The SMTP logs just show my successful connection attemps locally from
the server.

It is standard with one nic - no third party software other than anti-virus
and UPS, which I have disabled.

I also ran a port scan from another PC on the network, and the only open
ports between 1-100 were 21, 42, 53, 80, 81, 82, and 88.

I don't know what else I can check at this point, but I need to get
something working soon :)

Thanks again for the help!

Paul

If traffic between the client PC and the SBS isn't going through the DLink,
then that can't be the issue. Now we're down to something firewalling port
25 inbound on the SBS, right? Anything in the logs? Any 3rd party firewall
software installed on the SBS? Is it Standard or Premium with ISA? (Sorry
if you've already answered some of these).

If there's no 3rd party firewall, I'd run the CEICW one more time, paying
careful attention your choices for both firewall and Exchange. Then see if
you can telnet from the client PC again.

Hi Dave, thanks for the response!

I don't see how I can remove it, or how it would impact the situation. The
Dlink router is plugged into a 16 port switch via one of its LAN ports.
All
of the other client PCs are plugged into the same switch along with the
server. I don't think removing it would have any effect, as it is only the
default gateway for Internet access.

I'll give it a go just to be sure :)

Thanks again for the help!

If you can telnet to port 25 from the server but not from a workstation,
it's something between the workstation and the SBS. I'm guessing the
D-Link - can you remove that from the equation and see if you can then
get
in from a client PC?

Hi there Dave, thanks for the reply!

I just tried that, and the server did not respond from the client PC -
although from the server itself (telnet localhost 25) it did respond.

Strange - I reran the Connect to Internet Wizard, still the same
thing.
Strange huh?

What happens if you go to a client PC on the SBS LAN and try to telnet
into
Exchange? That'll let you know if Exchange is listening on port 25 -
if
it
responds normally, it's not an SBS-related problem. A possible
exception
would be something unusual with ISA allowing 25 on the internal NIC
but
not
on the WAN NIC, which would be fixed with the CEICW.

(Just open a cmd prompt and type "telnet <servername> 25" without the
quotes. It should return something like "220 mail.domain.com
Microsoft
ESMTP MAIL Service, Version: 6.0.3790.1830 ready at Tue, 27 Feb 2007
11:21:22 -0500").

Hi there,

I'm running into a weird problem with email on an SBS 2003 SP1 box.

All email is getting bounced back, and I can't seem to figure out
why.

Email is setup to be delivered directly to the server through the
wizard,
all DNS records are setup properly for this - when I use an online
MX
tool
the correct IP of the server is returned.

From the server itself, I run an online port scan tool, and it
reports
that
port 25 is closed. I have checked the DLINK firewall, and the port
is
forwarded correctly, and in the firewall log I see no requests to
port
25
being rejected during the port scan.

The only thing I can think of is that the smtp server on the box is
not
listening. I've disabled the anti-virus (McAfee Enterprise), and
still
nothing.

This is very strange because I have numerous SBS boxes setup exactly
the
same way, with no issues.

I'm hoping that someone out there can shed some light on this,
because
I
seem to be running out of options. Have I missed anything?

Thanks to all,

Paul
