+If nmh has been compiled with SASL support, the `\-sasl' switch will enable
+the use of SASL authentication. Depending on the SASL mechanism used, this
+may require an additional password prompt from the user (but the
+\*(lq.netrc\*(rq file can be used to store this password). The
+`\-saslmech' switch can be used to select a particular SASL mechanism.
+
+If SASL authentication is successful, \fIinc\fR will attempt to negotiate
+a security layer for session encryption. Encrypted traffic is labelled
+with `(encrypted)' and `(decrypted)' when viewing the POP transaction
+with the `\-snoop' switch.
