====qpsmtpd====
SME can be configured as a spam and antivirus filter for one or more "Internal" mail servers on a domain-by-domain basis. The mail server specified does not have to be on the same local network as your SME server.
+
SME uses the [http://smtpd.develooper.com qpsmtpd] smtp daemon.

=====Deliver ALL email to a single internal mail server=====
+
=====Official Description=====
You can deliver all email for all domains on your SME server to a single internal mail server by setting the mail server address in server-manager::Configuration::E-mail::Change e-mail delivery settings::Address of internal mail server.
+
qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core SMTP features, all functionality is implemented in small "extension plugins" using the easy to use object oriented plugin API.
   −
=====Deliver email for one domain to an internal mail server=====
+
qpsmtpd was originally written as a drop-in qmail-smtpd replacement, but now it also includes smtp forward, postfix, exim and maildir "backends".
You can also configure only a single domain to use an internal mail server, or you can configure different domains to use different internal mail servers.
     −
First, create the necessary virtual domains using server-manager::Configuration::Domains::Add Domain.
