24.9.86 PrivacyOptions
Increase privacy of the daemon V8.1 and later
The PrivacyOptions option is used primarily as a way to force other sites to adhere to
SMTP conventions, but can also be used to improve security.
The forms of the PrivacyOptions option are as follows:
O PrivacyOptions=what,... ?†? configuration file (V8.7 and later)
-OPrivacyOptions=what,... ?†? command line (V8.7 and later)
define(`confPRIVACY_FLAGS??,``what,...????) ?†? mc configuration (V8.7 and later)
Opwhat,... ?†? configuration file (deprecated)
-opwhat,... ?†? command line (deprecated)
Multiple what arguments are allowed but they must be separated from one another by
commas* (there can be arbitrary spaces around the commas). For example:
define(`confPRIVACY_FLAGS??,``authwarnings, needmailhelo????)
If this option is entirely omitted or if no what arguments are listed, the option defaults to
public. The default for the mc configuration technique is authwarnings. The possible what
arguments are listed in Table 24-23, and are described in more details in the sections that
follow.
* When the argument to an m4 define command contains one or more commas, that argument should be
enclosed in two single quotes.
