No such thing.<br />
<br />
Here's why...<br />
<br />
Every message sent may return a new SMTP response, unique across every single Mailbox Provider... like Gmail, Yahoo, Bigpond, etc...<br />
<br />
There is no... common list of SMTP responses + moment to moment, old messages may be replace by new messages.<br />
<br />
Like shooting a bow... from horseback... at a target attached to a drunk gopher...<br />
<br />
Likely you'll never hit the target.

I am trying to find a user friendly software that can explain SMTP logs to better understand what is going on with some emails. This is for an email relay server. We have some emails that didn't reach the other end but I do not see any errors on the logs. Is there anything you recommend?

SMTP log analyzer software

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

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.
