DEFAULT_MISC_OPTIONS

This configuration variable sets the default value for the Misc-Options keyword for all lists on the server.

When populated with one or more of the available values for the Misc-Options list header keyword, DEFAULT_MISC_OPTIONS sets a default for all lists that do not already have a Misc-Options setting. If a list has a Misc-Options keyword, the site-level setting is normally overridden. For instance, if you have DEFAULT_MISC_OPTIONS=IGNORE_EMAIL_CASE and a given list has Misc-Options= RESPECT_EMAIL_CASE, then the list-level option overrides the site-level option.

You may also prefix options in DEFAULT_MISC_OPTIONS with either a plus or minus sign (no space between the +/- sign and the name of the option). As before, an unprefixed option is active if the list owner did not specify any Misc-Options keyword and is otherwise ignored.

An option prefixed with a plus sign is always active for every list. There is no way for the list owner to turn it off.

Likewise, an option prefixed with a minus signed is prohibited and will be ignored if specified in the list header. Therefore something like DEFAULT_MISC_OPTIONS=-NO_SPAM_CHECK would disallow list owners from disabling the spam check for their list by setting Misc-Options= NO_SPAM_CHECK.

Multiple options for DEFAULT_MISC_OPTIONS are specified in the usual space-separated manner.

This configuration variable is not set by default.
