CAN'T SENDFROM OUTLOOK

[paule]

I have Office 2003/Outlook. When I am on my home network ( wireless or LAN) I
can send and receive emails but when I am in a hotel etc. I receive an error
message 550 or relay error. I can receive but not send. What should I do ?

You need to check with your ISP whether you need to authenticate your smtp
server...
