SSL CLIENT

TCP/IP-channel-specific options: SSL_CLIENT (0 or 1)
(New in 7.0.5) If set to 1, SSL/TLS negotiation will be performed immediately after any connection is established by the SMTP client  (without any use of STARTTLS). It is thus the client analogue of the Dispatcher&#x27;s   option (  Dispatcher option in legacy configuration) for  servers. The default for  is 0, meaning that such automatic  (non STARTTLS) SSL/TLS negotiation will not be done by the client. (Client negotiation via STARTTLS is a separate issue and may still be performed, depending upon configuration; see the    channel options.)

is useful for establishing point to point links to other systems using   on port 465. In particular, a typical use of the   option would be on a special tcp_&#x2a; channel that has    set; e.g.: msconfig&#x3e; show channel:tcp_ssl_friend.port instance.channel:tcp_ssl_friend.port = 465 msconfig&#x3e; show channel:tcp_ssl_friend.options.SSL_CLIENT instance.channel:tcp_ssl_friend.options.SSL_CLIENT = 1
