Access port 25 on ISP mail server from a client computrr

[allenj]

I have a client with a SBS 2003 and fir workstations. All stations can browse
the internet. The ISP issuer the pop3/smtp for email . I go into email
accounts from tools in the Outlook action bar at the work station and
configure the pop3 email account. Since the ISP requires authentication, I
check the appropriate box in the more options window. I finish the setup and
tehn get back in to the email setting and click on send a test email . The
pop3 and smtp servers found but the test message fails to send. I can go to a
command prompt on the server and run telnet to the mail serve IP address
follwed by a space and then 25 and I get the proper response. I do the same
from any of the work stations and the is no response. I have not installed
any of the SBS 2003 Premium modules (including ISA)on the server. However, I
can browse the internet from Internet Explore. It's the Outlook to the Isp's
pop3/smtp (specifically the mail server port 25 at the ISP) connection that
fails. Something is blocking that connection at the client. Does anyone have
any ideas as to how to isolate and fox the problem?

Thanks

Got a software firewall installed (could be part of an antivirus/security
package)?

Now, I have to ask--since you have SBS, and hence Exchange--why you're
setting up Internet mail accounts in Outlook. I'd make life easier for
myself and my users and let the Exchange server handle it all.

You might post in microsoft.public.windows.server.sbs for more SBS-specific
help.

The workstations were part of a peer-to-peer network and each has/had
Symantec Systemworks installed to filter viruses. I uninstalled Systemworks
on one workstation (did not run nonav.exe) and the problemm persists.

I set up pop3/smtp in Outlook because that is the protocol the ISP uses.
Also I have invoked the Pop3 connector in Exchange.

Thanks for the tip. I have posted the question in the SBS General section.
Something may drop out.

I suspect you may have some shards on it somewhere. Try a telnet when using
safe mode with networking.

I set up pop3/smtp in Outlook because that is the protocol the ISP
uses. Also I have invoked the Pop3 connector in Exchange.

But if you're using the POP connector, you don't need to set up Internet
mail accounts in Outlook - they should just connect directly to the Exchange
mailboxes via MAPI.

I'm not a big fan of the POP connector either, but it's surely better than
what you're trying to do now. At least it centralizes stuff in one place on
your network (and users can use OWA, etc)

Good luck in there.
