I should probably also mention that we have a smarthost (Smoothwall) which sits on the DMZ sending/receiving mails.

Hi All,<br />
<br />
I have just recently upgraded to Exchange 2007 (single server enviorment, no edge server) and we are now having some issues with our photocopiers sending network scanned documents to users outside of our internal domain.<br />
<br />
With Exchange 2003 the copiers were setup with SMTP authentication using an AD account that was created specifically for them. Now we have upgraded the copiers and no longer able to authenticate correctly using their credentials, I just get the error &quot;authentication failed, check your username and password&quot;. If I uncheck SMTP authentication I am able to send scanned documents from the copier to internal users but not to external users.<br />
<br />
I assume that this has something to do with the recieve connector but I cannot find the correct settings, any ideas?

Hi All,

I have just recently upgraded to Exchange 2007 (single server enviorment, no edge server) and we are now having some issues with our photocopiers sending network scanned documents to users outside of our internal domain.

Now we have upgraded the copiers and no longer able to authenticate correctly using their credentials, I just get the error "authentication failed, check your username and password".

Exchange 2007 and Legacy SMTP Authentication

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.

Email Protocols

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.

Exchange

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.
