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. perl v5.16.3 2011-06-06 Mail::SpamAssassin::Plugin::MIMEHeader(3)
