Controlling LAN email

kylep
Hi,

I've started working at a small company which has a Windows 2000 Server, with Exchange 5.5 installed.

I have created mailboxes on a POP3 server offsite with our ISP and changed the MX records for our domain. The POP3 mailboxes work perfectly and use the same email addresses as the users had previously when they used Exchange.

I've removed the exchange server from the user's Outlook (not the server yet), but when they try to send to another user's POP3 address (using the SMTP of the ISP's mail server), the mail never leaves the LAN and is stored on the exchange server.

I've tried disabling all Exchange services, but the same thing happens. I've tried removing the mailbox from Exchange, but then I get an error telling the user that the recipient cannot be found.

What I would like is all mail to leave the LAN and not be touched by anything other than the firewall!

Could you please help, this is driving me nuts!

    The PC cannot reach the SMTP server directly. Outgoing messages have to be relayed to it. You must either configure Exchange to relay SMTP (forwarding), or shut it down so that those relay requests are answered by your ISP's SMTP servers (which may require authentication). Make sure port 25 is specified for SMTP in both Outlook advanced settings, as well as the open port on your firewall.

    If I shutdown the PDC with Exchange on it and send an email through the lan with while the BDC on, I get no error messages but the mail doesn't reach the recipient until I start the PDC again then the mail comes through.

    Has this nothing to do with Active Directory???

    After stopping all exchange services, the mail doesn't get past the PDC even when trying to send with my ISP's SMTP server.

    How can I stop this?
