SMTP problems using CDO
 
Hi all,
I have created a tool which sents mails to customers where I use CDO to
generate the mails from Excel data and sent it throu the corporate Exchange
server.
The problem is, when I am sending to the internal adresses (used by our
compay), everything works fine, but when I try to sent it to a public mail
adress I get an error which states, that this email adress hasnÂīt been
recognized...

Any ideas how to fix it ???

I thought about including an authentication dialog into the code, but I
think it wont help because I am able to sent emails internaly.
