+=head1 NAME
+
+Qpsmtpd::Connection - A single SMTP connection
+
+=head1 SYNOPSIS
+
+  my $rdns = $qp->connection->remote_host;
+  my $ip = $qp->connection->remote_ip;
+
+=head1 DESCRIPTION
+
+This class contains details about an individual SMTP connection. A
+connection lasts the lifetime of a TCP connection to the SMTP server.
+
+See also L<Qpsmtpd::Transaction> which is a class containing details
+about an individual SMTP transaction. A transaction lasts from
+C<MAIL FROM> to the end of the C<DATA> marker, or a C<RSET> command,
+whichever comes first, whereas a connection lasts until the client
+disconnects.
+
+=head1 API
+
+These API docs assume you already have a connection object. See the
+source code if you need to construct one. You can access the connection
+object via the C<Qpsmtpd> object's C<< $qp->connection >> method.
