We send and receive email from around the world. <br />
<br />
We are in the process of changing our MX records however..... I am not positive when ( some time in the next month ). &nbsp;<br />
<br />
I know a little about changing the time to live for mx records and am not sure I want to go from 24 hours to one second in just one step. &nbsp;I am looking for an logical TTL that will keep us running in mail around the world but is not a 24 our setting. &nbsp;It would be a setting that some people run on a daily basis. &nbsp;<br />
<br />
My top candidates for time to live are 2 hours, or 1 hour. &nbsp;<br />
<br />
How would you step the time down ? &nbsp;<br />
<br />
24 hours, 2 hours, 1 hour, 1 second ? <br />
<br />
24 hours, 1 second ? <br />

MX records and changing a mail server

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.

Internet / Email Software

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.
