I guess it is used to scan email that comes in, but I see exchange information store service running on the server. Does it mean there is full blown exchange installed there with Databases?<br />

I guess it is an SMTP relay

I amnot sure why it is blocking emails going out to the internet?<br />
It makes sense when it blocks emails coming in from outside to inside, but not the other way around.

<div class="content wysiwyg-content">
we have an exchange server 2003, they call SMTP server, but I am not sure the right role it has.<br />
it has exchange 2003 installed on &nbsp;it. I know that the email goes through it to internet.<br />
But there is confusion in SMTP roles:<br />
SMTP connectors<br />
SMTP Gateway<br />
SMTP virtual servers<br />
Smart Host<br />
SMTP Relay<br />
........and maybe more<br />
<br />
I know I have given you too much info, that I need to find out, but I know that emails sent to internet go through this server, and this server is called an smtp server.<br />
<br />
Any way to find the right role of this server?<br />
<br />
thanks

Exchange 2003 SMTP

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

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

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
