We're using SBS 2003 with Exchange 2003 in our office. We relay outgoing messages thru a 3rd party smarthost. It works fine. I'm looking at the Advanced tab, Outbound security, and we are set for Basic authentication (username and password are supplied). Where are the settings stored for the SmallBusiness SMTP connector? Are they in the registry? Do they reside in an ini file somewhere? I'd like to be able to update/change the supplied username & password dynamically if possible...

Hello,Basic authentication:In the context of an HTTP transaction, the basic access authentication is a method designed to allow a web browser, or other client program, to provide credentials in the form of a user name and password when making a request.Now when you say "We relay outgoing messages thru a 3rd party smarthost - it works fine". It has to be because the 3rd parth application listining to 25 SMTP and i guess there is a relay permission has been give to your exchange outbound connecting IP, other wise you will get 5.7.1 NDR ( Unable to relay ).Now when you say - I'd like to be able to update/change the supplied username & password dynamically - how do you wanna achieve this? - by a custom coding?

Hi, The username and authentication method is saved as attributes of the SMTP connector object.For example, the msExchSMTPOutboundSecurityFlag is used to configure the authentication method. The msExchSMTPOutboundSecurityUserName is used to save the UserNameMike

So I should be able to set msExchSMTPOutboundSecurityUserName and msExchSmtpOutboundSecurityPassword using a script? I'm a little behind the times with Windows scripting, can you give me an example of how to do this?

Hi, I would like to explain that regarding development question, I suggest you post your question in development forum: http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads In addition, would you please let me know why you need to write script to the update the AD attributes? I think that you can simply configure the third-party smarthost to allow the SBS Server to relay email through the Smarthost. Mike

Still trying to write a script to change those settings in AD. Any help would be appreciated!
