I've tried reading some articles but I need help fast - our email is down.

We've been running Exchange 2003 on our SBS 2003 server for months now POP-ing our ISP's mail server and suddenly at 6:01 AM today our server stated logging the following errors and it is no longer downloading mail via the POP3 connector:

Event ID: 1036
Source: POP3 Connector
"An error occurred during a POP3 transaction to the server <.x.x.x.x>. The error is 10060 (A connection attempt failed because the connected third party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Event ID: 1036
Source: POP3 Connector
"An erroroccurre during a POP3 transaction to server <x.x.x.x>. The error is 10061 (No connection could be made because the target machine actively refused it.)"

I'm racking my brain. Please help. Thanks!

    Those errors suggest something wrong with the POP3 server or POSSIBLY the connection to it.  Have you called your ISP that runs the POP3 server?  Have you tried to access the account directly, instead of via the Exchange POP3 client?  Have you tried to ping the POP3 server to verify it's on (a no response may NOT mean it's off if they have a firewall on it and a Reply may NOT mean it's on as the service itself may be having problems - ultimately this is why you need to call the ISP.

    I'm on hold with the ISP right now. Thanks.

    Our host changed the IP address of our mail server without telling us. Thanks for your help though.
