ClientPortOptions
Client port option settings V8.10 and later
The sendmail program can run in
two connection modes: as a daemon, accepting
connections; or as a client, making connections.
Each mode can connect to a port to do its work. The
options for the daemon port are set by the DaemonPortOptions option
(DaemonPortOptions on page 993).
The options for the client are set by this ClientPortOptions

options for the outgoing connection. The form for
this option is as follows:
O ClientPortOptions=pair,pair,pair ← configuration file (V8.10 and later) -OClientPortOptions=pair,pair,pair ← command line (V8.10 and later) define(`confCLIENT_OPTIONS',``pair,pair,pair'') ← mc configuration (V8.10 through V8.11) CLIENT_OPTIONS(``pair,pair,pair'') ← mc configuration (V8.12 and later)
The ClientPortOptions option is followed by
a comma-separated list of pairs,[367] in which each pair is of the
form:
key=value
The complete list of key and value pairs is can be found under the
DaemonPortOptions option (see DaemonPortOptions on page 993). All of
those pairs apply to this option, except the
Listen key. The
flags set by the ClientPortOptions option are saved in
the {client_flags} macro (${client_flags} on page 812) and are thereby made available to
rule sets.
As of V8.12, you can have multiple ClientPortOptions option
declarations, one per Family key type. That is, for example, one for the family of IPv4 addresses, and another for the family of IPv6 addresses. ...
