Suggested Answer: D 🗳️
Note:
* sendmail
* Enabling Access to Remote Clients
On an unmodified system, access to sendmail by remote clients is enabled and disabled through the service management facility (see smf(5)). In particular, remote access is determined by the value of the local_only SMF property: svc:/network/smtp:sendmail/config/local_only = true
A setting of true, as above, disallows remote access; false allows remote access. The default value is true.
The following example shows the sequence of SMF commands used to enable sendmail to allow access to remote systems:
# svccfg -s svc:/network/smtp:sendmail setprop config/local_only = false
# svcadm refresh svc:/network/smtp:sendmail
# svcadm restart svc:/network/smtp:sendmail
Reference: man pages section 1M: System Administration Commands, sendmail
