+If
+.B nmh
+has been compiled with SASL support, the
+.B \-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
+.RI \*(lq \&.netrc \*(rq
+file can be used to store this password). The
+.B \-saslmech
+switch can be used to select a particular SASL mechanism.

+If SASL authentication is successful,
+.B inc
+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
+.B \-snoop
+switch.
