Not at all. Stunnel is not a smtp proxy: it does not deal with applicative protocols in general (higher than level 3 osi, ie tcp/ip). But it can be used, implemented both at the server side AND client side, to tunnel SMTP traffic in SSL tunnel , thus emulating "SMTPS". Yours sincerely, Pierre Quoting John Conover <conover@rahul.net>:

Can stunnel be used for a local smtp server, that does not support upstream SMTP AUTH, to connect to an smtp server that requires it?

Thanks,

John
