Hehe, the same problem again :)

Please read this first:

You can follow the steps mentioned in the above link so that your internal
client can sent mails to the ISP MBXs. Make sure that the MX records point
to SMTP of the internal Exchange server, not the ISP's. You should also ask
ISP MBX clients to use authenticated and encrypted connection to internal
Exchange SMTP to send mail.
