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

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

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
