Hello,

I'm currently running SBS2003 and have configured a VPN connection to my
network. After I establish an Internet connection and successfuly login in
using my VPN client I have access to my network including my Exchange Server.
 All my emails are downloaded to my Outlook 2003 client and I'm able to read
them without any problems; however, when I attempt to send a message I
receive this dreaded undeliverable message: #5.5.0 smtp;530 Authentication
required. If anyone knows a fix or a workaroud it will be greatly
appreaciated.

Thanks,
Ralph R.
