SocketMail can be integrated with your existing MTA (acronym for Mail Transfer Agent) on your server such as Exim, Qmail, Postfix or Sendmail. The integration involves manual process of modifying the MTA configuration file. This require certain level of knowledge in managing your server system.
With MTA integration process, you may define selected domains to be receive and process by SocketMail engine whilst the rest of the domains on your server still continue to have their mails managed and process by the existing MTA.
MTA integration is require when you are unable to run SocketMail daemons due to inavailability of the PCNTL module (see Daemons) in your PHP.
