I have just installed a Small Business Server 2008 network and the client has been using a CRM program that previously used an external SMTP server to generate mass amounts of emails to clients. The software now has to be adjusted so that it is sending out via an account on the SBS08 server. Unfortunately it only has options for server name, username and password, with no option for SSL or port numbers.<br />
<br />
I am currently getting SMTP 550 5.7.1 errors about not being allowed to relay as the current user.<br />
<br />
So I have to change the email sending requirements in Exchange to not require SSL connections, to accept via the default port of 25, and use plain text authentication. I went into Server Configuration &gt;&nbsp;Hub Transport &gt;&nbsp;Receive connectors &gt;&nbsp;Windows SBS Internet Receive connector, but I'm not sure if I'm changing settings in the correct area and I don't want the server open to relaying. Any assistance would be appreciated.<br />

Change SMTP security requirements for Exchange 2007 to not require SSL

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
