+/*++
+/* 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
+/* .fi
