Hello everyone,

I just installed Exchange 2000. The problem I am having is that I cannot send email out (i.e. hotmail.com or yahoo.com) from POP3 setting - the POP3 and SMTP settings are pointing to my new mail server domain name. I had my ISP add an MX record to point all mail to my new domain mail server. I could send email out from OWA to the outside world but not from POP3. What am I missing? Please help.

Thanks in Advance,
areyes

" Some ISP's require your system to issue a command to identify itself to the provider and to notify it that messages can be sent. you can configure your system to use ETRN,TURN to issue the custom command. IMS can also be configured to RAS to connect to your ISP via Rcp. MMC is used to configure POP3, SMTP,IMAP4,LDAP NNTP properties. Recheck all connections including the Virtual server redirects to POP3,SMTP,IMAP4,LDAP & NNTP local and remote IP/port assignments. Command line syntax, Netstat-an -p -TCP can help you identify open, closed TCP,UDP IP addresses and ports.

Exam Cram Exchange Server 2000 supplement is a good book to polish up knowledge on Exchange Server 2000 installation, administration, maintance and trouble shooting.

for the CMD line syntax mentioned above, at the prompt type: netstat-an-ptcp. This will provide you a list of all TCP UDP IP addresses and port numbers and their status. You can Telnet any of the IP addresses and port numbers todetermine port status.

Just a thought. Since your using SATCOM you should check your uplink outbound interlever synchronization to your downlink inbound de-interlever. Non synchronization with the interlever/de-interleaver will result in critical error dropped packets.

Your exchange server is working correctly. If you setup outlook to use exchange, instead of pop3 it will work because OWA works. there can be many answers, but I will assume the most common one. Exchange 2000 by default does not allow sending mail without authenticating over smtp. When you send out the message I am assuming that you get back a 550 error. In your POP3 and SMTP server settings, set authentication to send mail. Under "Outgoing Mail Server", Click the checkbox "my server requires authenticaton"

You should post the exact error message you get when sending mail. This will help us, help you.

Thanks for the answer. The error was exactly what you have mentioned. All it needed is that checked to the Outgoing Mail and it did the trick. Thanks very much!

as per your references to owa your exchange is working perfectly and only for smtp settings or not working from clients that was to delivered to clients in out side world or inside world i think your have to configure smtp settings as ur system ip address not server address, the server will do remaining things.

i hope this will solve your problme

i hope this
