DISCUSSION_REJECT_HEADERS

The DISCUSSION_REJECT_HEADERS variable allows you to block different headers submitted by email that contain arbitrary strings.

Values

Regular expression

Default

None

Example

DISCUSSION_REJECT_HEADERS=(?s).*headername1:value2.*,(?s).*name2:value2.*

Comments

Add one or more header names. Each regular expression must match an entire header name. The match of any of these headers in an incoming message (via email)causes its rejection, with appropriate notification to the posting user.
