+/* NAME
+/*	smtputf8 3
+/* SUMMARY
+/*	SMTPUTF8 support
+/* SYNOPSIS
+/*	#include <smtputf8.h>
+/*
+/*	int	smtputf8_autodetect(class)
+/*	int	class;
+/* DESCRIPTION
+/*	smtputf8_autodetect() determines whether the cleanup server
+/*	should perform SMTPUTF8 detection, depending on the declared
+/*	source class and the setting of the smtputf8_autodetect_classes
+/*	configuration parameter.
+/*
+/*	Specify one of the following:
+/* .IP MAIL_SRC_MASK_SENDMAIL
+/*	Submission with the Postfix sendmail(1) command.
+/* .IP MAIL_SRC_MASK_SMTPD
+/*	Mail received with the smtpd(8) daemon.
+/* .IP MAIL_SRC_MASK_QMQPD
+/*	Mail received with the qmqpd(8) daemon.
+/* .IP MAIL_SRC_MASK_FORWARD
+/*	Local forwarding or aliasing.
+/* .IP MAIL_SRC_MASK_BOUNCE
+/*	Submission by the bounce(8) daemon. 
+/* .IP MAIL_SRC_MASK_NOTIFY
+/*	Postmaster notification from the smtp(8) or smtpd(8) daemon.
+/* .IP MAIL_SRC_MASK_VERIFY
+/*	Address verification probe.
+/* DIAGNOSTICS
+/*	Panic: no valid class argument.
+/*
+/*	Specify one of the following:
+/*	Warning: the smtputf8_autodetect_classes parameter specifies
+/*	an invalid source category name.
+/* LICENSE
+/* .ad
