Hello all, found this link from WOWN.COM. I've begun installing some SBS servers, glad I found this site.

I've generally installed SBS2K servers without using ISA for the most part, just single NIC servers. I have one home which is single NIC, I use the POP3 connector to pull down my POP3 e-mail from my ISP, and deliver to my Exchange box. Same at the office.

Now a setup I just put in last week....it's an SBS2K Server, dual NICs, using ISA, with the WAN NIC behind a NAT router on DSL. I setup the POP3 connector to download several mailboxes and deliver to the appropriate Exchange users...but it fails to grab the e-mail. Event Viewer shows an error relating to Event ID 10065...which Microsoft only lists as a name resolution problem on SBS4.5. This is an SBS2K server, latest service packs and all.

I setup the ISA through the internet connection wizard...also had to manually allow POP3 requests out for the users currently using Outlook Express....did that following an article I found here.

But my guess is...ISA is blocking the Exchange Server POP3 connector from going out and contacting mail.nameoftheirmailhost.com

Hi!

Do you use the Microsoft Exchange Connector for POP3 Mailboxes? I believe u can only use that one with SBS4.5 and not with SBS2k.

Greetings,

I'm using the POP3 connector that's built into SBS2000...set to download every 15 minutes. It's fully supported, and quite easy in SBS2K...I've set it up on non-ISA SBS2K installations, with only 1x NIC. This is my first going through 2x NICs and ISA....and something in ISA is stopping it from going out to retrieve e-mail from the mailhost every 15 minutes.

Hi YOS,

Create a packet filter to allow outbound access to TCP 110.

HTH,
Tom

Just to double check....didn't following the advice on the following link perform your above suggestion already?

Hi YOS,

That article applies to internal network clients who want to use Outlook Express to access external network mail services.

For services and client applications running on the ISA Server, you sometimes need to configure packet filters to allow them to work. For example, if you want to allow Outlook Express on the ISA Server itself to work (which is definitely *not* a best practice), you would have to create packet filters to allow SMTP and POP3. If you wanted to allow Exchange to use a POP3 connector, you would have to create a POP3 packet filter, because that Exchange connector is acting as a POP3 client application.

HTH,
Tom

Hi YOS,

The packet filter log should show the blocked POP3 packets. What is the exact config of your packet filter?

Thanks!
Tom

Hi YOS,

The default POP3 packet filter only allows inbound access.

HTH,
Tom

You have to add a Filter to allow POP3 IN/OUT as well as add mail.nameofthisplace.com to your Proxy exceptions list in internet explorer > tools > Internet Options > Connections > LAN Settings > advanced. The Reason for this is because Exchange is using the System account which does not have internet privilages.
