-Gmail only supports POP3 over TLS, but
-.B inc
-has no TLS support. To work around this, use something like
-.B -proxy 'openssl s_client -connect %h:995 -CAfile /etc/ssl/certs/ca-certificates.crt -quiet'
+If
+.B nmh
+has been compiled with TLS support, the
+.B \-initialtls
+switch will require the negotiation of TLS when connecting
+to the remote POP server. The
+.B \-initialtls
+switch will negotiate TLS immediately after the connection has taken place,
+before any POP commands are sent or received. Data encrypted by TLS is
+labeled `(tls-encrypted)' and `(tls-decrypted)` with viewing the POP
+transaction with the
+.B \-snoop
+switch. The
+.B \-notls
+switch will disable all attempts to negotiate TLS.
+.PP
+When using TLS the default is to verify the remote certificate and SubjectName
+against the local trusted certificate store. This can be controlled by
+the
+.B \-certverify
+and
+.B \-nocertverify
+switches. See your OpenSSL documentation for more information on certificate
+verification.
