It’s BROKEN. I’ve tried this many times, in many ways.

We can’t unsubscribe you, but you’ll find these in the headers for  
most mailing lists. The List-Unsubscribe header is telling you to  
send an email to removed\_email\_address@domain.invalid with ‘unsubscribe’ in  
the body.

Unsubscription isn’t actually broken; there are feature limits. One of  
those may be that your mail client sends messages in quoted-printable  
format (I checked this against the original format in gmail) as  
opposed to simple plain ASCII. I know that people who use gmail have  
had problems when they send their messages in UTF-8 because the  
messages are encoded base64.

Or just call ([http://opensource.bertram-scharpf.de/sites/cropmail](http://opensource.bertram-scharpf.de/sites/cropmail)):

mymessage.decoded =~ /…/u

Regarding multipart messages (untested):

class Cropmail::Message  
def body\_matches re  
if is\_multipart? then  
each { |p,invisible| # invisible is preamble or epilogue  
return p.body\_matches re unless invisible  
}  
else  
decoded =~ re  
end  
end  
end

mymessage.body\_matches /…/u

Time for a Ruby ML Server?
