Not Entirely sure I am reading your correctly, but almost any mailserver can allow local users to send mail AND allow authorized external IPs to relay mail outbound.<br />
<br />
There are plenty of free MTAs - I prefer Exim, but that's mostly just personal preference.<br />
<br />
If you can go into more detail on what you are trying to achieve?

Hi, Well what I want to do is that I have a few devices in my house, such as dvr and network cameras. Instead of configuring the SMTP email settings pointing to my providers SMTP on each device to send me notifications, I would like the smtp server settings on the devices to point to an internal computer in my house and then configure my external SMTP settings in the relay software to send those messages out. Kind of like a router.<br />
<br />
Thank you.

Hi Team,<br />
<br />
I would like to install an email replay software in one of my servers where I can configure a primary smtp server use for sending emails, at the same time, allow my internal server to relay messages off this application to the smtp server configured. Is this possible, any free application out there?<br />
<br />
Thank you

Email Replay software needed

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.

Email Servers

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.

Email Software

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.
