Hello,

I do have a MS Proxy 2 on NT4 as a 'caching only' server. I can not get POP3 working using Outlook 2000 (internet mail). Web traffic is running perfect. Telnetting a pop account from the proxy works good.

I have checked the mspclnt.ini file:

[explorer]
Disable=0
[outlook]
Disable=0
[mapisp32]
Disable=0

I have read the tips and faqs on http://proxyfaq.networkgods.com and the support.microsoft.com.

I'm stuck here...

I'm steeling this but maybe it will help you.

We installed Microsoft Proxy Server 2.0 as a firewall and proxy solution for our network. Since the installation, we can use Outlook Web Access (OWA), but we haven't been able to usePOP3 clients. The OWA and POP3 clients come in over the Internet. Does Proxy Server 2.0 prohibit POP3 access to Exchange Server from working? If so, how can I work around this problem?

When you install a proxy server or firewall, you isolate yourLAN from the Internet. The proxy server passes in or out only the traffic types you specify. You have to configure the proxy server to allow POP3 traffic from the IS service. To add POP3 to the list of protocols the proxy server can support, make sure you have a separate proxy server configuration file just for the IS service. Create a wspcfg.ini file, and put it in the same location as your store.exe file (usually in \exchsrvr\bin\). The file looks like this:

[STORE]
ServerBindTcpPorts=110
Persistent=1
KillOldSession=1
You need the 110 in the second line because POP3 traffic is carried on port 110. To add Network News Transfer Protocol (NNTP) or Internet Message Access Protocol (IMAP), add their port numbers (119 and 143, respectively) to that line. The Microsoft article "How to Configure Exchange or Other SMTP with Proxy Server" (http://support.microsoft.com/support/ kb/articles/q181/4/20.asp) provides more information about configuring Proxy Server 2.0 for use with Exchange Server.

Don't trust Daffy.

I want users 'inside' to connect to a ISP outside.... How changing the Exchance setting will help is not clear to me. This also counts for the IIS.

As far I can see your referring to the situation a Exchange server is behind the Proxy server.

The current settings:

- Winsock 8080
- User is member of group in enable accesscontrol > unlimited access.
- pop3 110 - outbound - tcp / port 0 - inbound - tcp
- telnet 23 - outbound - tcp/ port 0 - inbound - tcp
- smtp (client) 25 - outbound- tcp / port 0 - inbound - tcp

In the log I see:

%ip_number%, %username%, -, Y, 8/22/02, 14:59:35, 2, -, -, %site_name%, -, -, -, -, -, -, -, -, -, -, -, 0, 0

So the proxy does receive but then just drops it. I'm sure I'm just overlooking something but cant see it :-(
