Cannot send mail with Netscape or Outlook Express 1

[Creeker]

We use Exchange Server 5.5 to handle our email on a LAN through a DSL connection. We use Outlook 2000 as our mail program. I would like to set up Netscape to also be able to send mail through this DSL connection, but I cannot get it to work.

I set the incoming mail to our server name and server type to IMAP. For outgoing I entered the server name and the user name. It reads the mail correctly and pulls in the inbox from the server. When I try to send mail, it is returned from the system administrator as undeliverable, saying the recipient is not recognized.

Have you got the routing tab on your IMC set up correctly, you need to have the 'Reroute incoming SMTP mail (required for POP3/IMAP4 support)' radial button checked.

Thanks for your reply, GWINTO. I finally figured out that this was the case. When the outside vendor setup up our DSL connection, they apparently changed this setting. I changed it back and everything works fine now.

Remember your server may be used as a Relay if you route messages.

I know. I have it set to only those who successfully authenticate. Is this enought protection? What more can I do? Can't send mail from other programs otherwise.
