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.
