Hi,
I'd like to know if it is possible to configure Sendmail as a client
using SSL without STARTTLS -- what I'm trying to set up is a sendmail
that authenticates itself to a mail hub either using SMTP AUTH over SSL
or certificates, knowing that the server at the other end directly
begins an SSL negotiation (i.e. *no* STARTTLS) -- I'd rather not resort
to stunnel-like solutions if possible.
And yes, the server does have to support some Outlook clients ;-)

I had the same problem. The solution is to add the following to your
sendmail.mc and regenerate your sendmail.cf. Port 465 is for smtps,
which is apparently depreciated, but Microsoft products seem to work
with it.

DAEMON_OPTIONS(`Port=465, name=SSA, M=Es')

You have provided recipe how to make sendmail accept incoming SSL (not
STARTTLS) connections. As I understand the question was about *outgoing*
SSL connections.
