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.
