Trouble setting up email with Exchange 2007

[smartin52000]

During the initial install phase I had trouble setting up email with the "installer.pl", it could not communicate with my Exchange 2007. I tried IMAP, POP3, Secure IMAP, and Secure POP3. After searching Google, one suggestion was to create a receive connector within the "Hub Transport" of Exchange with "Basic Authentication, and permissions for "Anonymous Users, Exchange Users, and Exchange Servers".

Below is the error when I try to fetch mail from the Postmaster/Mail Accounts from the Admin section, this is an account I setup within Exchange:

Backend ERROR: OTRS-CGI-10 Perl: 5.10.1 OS: linux Time: Mon Jul 2 16:38:21 2012 Message: POP3: Can't connect to rncmailhub.rnewhope.org Traceback (4228): Module: Kernel::System::MailAccount::POP3::Fetch (v1.9) Line: 128 Module: Kernel::System::MailAccount::MailAccountFetch (v1.17) Line: 424 Module: Kernel::Modules::AdminMailAccount::Run (v1.28) Line: 69 Module: Kernel::System::Web::InterfaceAgent::Run (v1.64) Line: 868 Module: ModPerl::ROOT::ModPerl::Registry::opt_otrs_bin_cgi_2dbin_index_2epl::handler (unknown version) Line: 46 Module: (eval) (v1.90) Line: 204 Module: ModPerl::RegistryCooker::run (v1.90) Line: 204 Module: ModPerl::RegistryCooker::default_handler (v1.90) Line: 170 Module: ModPerl::Registry::handler (v1.99) Line: 31

I am able to initiate communication with "telnet exchange_server_name 25".

Any thoughts on why I am unable to communicate with Exchange?

Thanks,

check the ports for pop3, imaps and the static ssl ports for these protocols.

Port 25 is for sending mails (smtp) and not for fetching them

Try "telnet rncmailhub.rnewhope.org 110" Chances are it does not connect.
If it doesn't, you'll need to make sure your transport for POP3 (and appropriate service is started) allows your OTRS box to retrieve email via POP3.
