There are two different filters at # Privacy options... ->Spam filters,
and they work differently.
The more flexible of the two is header_filter_rules. For
header_filter_rules the regexps are matched against a multi-line
string containing all the unfolded headers in the message, both
message headers and sub-part headers. The regexp is a python regexp
the headers are searched
<http://docs.python.org/library/re.html#re.search> for a match of the
regexp in MULTILINE and IGNORECASE mode. This means the '^' matches
the beginning of the string or the null character immediately
following a newline and the match is case insensitive. Thus your above
expressions look good.
The other is bounce_matching_headers which works differently. It
expects a header name followed by a colon followed by a regexp to
match against the contents of that header - e.g.
subject:is out of office
would match any subject: header that contained 'is out of office'. This
match too is case insensitive.
Also, with bounce_matching_headers, you can't specify an action. The
action is always 'Hold'.
