Mail::SpamAssassin::Plugin::MIMEHeader(3)		User Contributed Perl Documentation		 Mail::SpamAssassin::Plugin::MIMEHeader(3)

NAME

       MIMEHeader - perform regexp tests against MIME headers

SYNOPSIS

	 loadplugin    Mail::SpamAssassin::Plugin::MIMEHeader
	 mimeheader    NAME_OF_RULE    Content-Id =~ /foo/

DESCRIPTION

       This plugin allows regexp rules to be written against MIME headers in the message.

RULE DEFINITIONS AND PRIVILEGED SETTINGS

       mimeheader NAME_OF_RULE Header-Name =~ /pattern/modifiers
	   Specify a rule.  "NAME_OF_RULE" is the name of the rule to be used, "Header-Name" is the name of the MIME header to check, and
	   "/pattern/modifiers" is the Perl regular expression to match against this.

	   Note that in a message of multiple parts, each header will be checked against the pattern separately.  In other words, if multiple
	   parts have a 'Content-Type' header, each header's value will be tested individually as a separate string.

	   Header names are considered case-insensitive.

	   The header values are normally cleaned up a little; for example, whitespace around the newline character in "folded" headers will be
	   replaced with a single space.  Append ":raw" to the header name to retrieve the raw, undecoded value, including pristine whitespace,
	   instead.
