i have a 5 client net with sbs exchange 2003.

for outbound mails I use a smtp connector.
The Smarthost is my ISP

That worked fine with smtp port 25

Now my ISP ask for authentication and port 587
Authentication i ve set in the connector settings
Port 587 i have set in the default smtp virtual server protocol

but the thing not work... outgoing mails are rejected with "relay problems"

any idea on this...

or does anybody know how to set up a connector who use DNS to send mails directly...

thx

It's been a few years but following: http://support.microsoft.com/kb/265293 can you not enter credentials?

Configuring the port is done via SMTP Virtual Server settings. The Default SMTP VS uses port 25. You'll need to create a new SMTP VS, then configure your Connector to use that VS instead.
