Hi guys,<br />
<br />
I am having problem in one of our domains which has just one DC and 5 computers. When a user sends an email to an incorrect email address, he is not getting any bounce back about that and he should. The server has GFI Mail Essentials installed and configured.<br />
Any idea what could be the problem? If you need more info, please let me know.<br />
<br />
Thanks,<br />
<br />

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.

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
