POP3 and FRONT END

POP3 and FRONT END

Post by Rusto » Tue, 01 Jul 2003 12:14:48



Hi I have two Exchange 2000 servers in a front end / backend configuration.

Should the front end server proxie POP3 requests to the backend server.
This keeps failing.

POP3 and FRONT END

Post by Rob Wilcox [MSF » Fri, 04 Jul 2003 06:13:49


Hi Rustom,

Yes it should.  In a front-end back-end configuration you should ensure
that the front-end server has the tick box on the properties of the server
object in Exchange System manager to indicate that it is a front-end.  You
should also ensure that there are no mailboxes on the front-end.

If you're seeing failures, please provide mor details.  Can you include the
Exchange build, and service pack level, as well as the Windows build and
service pack level.  Do you have any third party software components
installed on either the front end or the back-end?  If so, which products,
and version numbers?  Are you seeing anything written in the application or
system event logs with regards to the failure?

Kind Regards,

1. Front-End POP3 Virtual With Clients Using SPA

History:
My company is moving from Exchange 5.5 to Exchange 2000.  I have 500
clients connecting to E55 using Outlook 98 Internet Only using POP3
SPA (Secure Password Authentication). The E55 server is dual homed
with an IP I want to move to our E2K front-end servers (using NLB).

Problem:
I have created mailboxes on the clustered back-end.  When I use SPA to
the E2K front end, the POP3 session fails.  I can successfully
retrieve mail when I don't use SPA.

Removal of NLB produces same results.  There is no firewall in the
picture.  All POP3 virtual servers are set to allow Windows Integrated
Authentication.

My Exchange 2000 Servers are at SP1 and Windows 2000 SP2.  I am in
mixed-mode with three E55 servers and six E2K servers.
