+If nmh is using the SMTP MTA, the
+.B \-server
+and the
+.B \-port
+switches can be used to override the default mail server (defined by the
+.RI servers
+entry in
+.I %etcdir%/mts.conf

+.PP
If
.B nmh
has been compiled with SASL support, the
switch can be used to select a authorization userid
to provide to SASL other than the default.

-Currently SASL security layers are not supported for SMTP.
-.BR nmh 's
-SMTP SASL code
-will always negotiate an unencrypted connection. This means that while the SMTP
-authentication can be encrypted, the subsequent data stream can not. This is in
-contrast to
-.BR nmh 's
-POP3 SASL support, where encryption is supported for both the
-authentication and the data stream.
+If SASL authentication is successful,
+.BR nmh
+will attempt to negotiate a security layer for session encryption.
+Encrypted data is labelled with `(encrypted)' and `(decrypted)' when
+viewing the SMTP transaction with the
+.B \-snoop
+switch.
