Good day<br />
<br />
I have to upgrade PostFix Admin from 2.2.1.1 to 2.3.3<br />
Was searching on WEB, did not find much<br />
It is a production PostFix server with MySql to store all settings <br />
Step-by-step plan would be highly appreciated<br />
<br />
Thank you<br />

PostFix Admin upgrade from 2.2.1.1 to 2.3.3

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.
