Hi there, <br />
<br />
We need to find a way of load balancing php sendmail, we are using some e-mail marketing software that connects to our SMTP server - but because we send millions of e-mails we find that it takes days to send. <br />
<br />
Any suggestions as to how we would load balance sendmail across all of our centos 5 &amp;&nbsp;6 servers? <br />
Ideally I'd like to load balance them over 10 servers - but I am open to literally ANY suggestions! <br />
<br />
Thanks,

Load Balancing SendMail ?

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.

By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
