The "client" setting does not depend on whether you run stunnel as
a service or not; the only thing it depends on is what role you
want stunnel to play in the TLS tunnel.  When stunnel runs in
client mode, it accepts unencrypted connections from other programs
(e.g. an e-mail client) and establishes a secure tunnel to a TLS
server to send the data encrypted over the network.  When stunnel
runs in server mode, it accepts encrypted connections over
the network, decrypts the data, and sends it to a server that does
not know how to or does not want to handle the TLS encryption by
itself.

If you know that you want to run stunnel in server mode (let it
accept TLS connections, decrypt the data and hand it off to some
server-like application to process it), then it is "client = no".

G'luck,
Peter
