Because you have trained a lot of spam with that token.  It really is  
that simple.

'header:Reply-To:1' says that there is exactly one "Reply-To" header;  
it does not say anything about its contents.

You can stop SpamBayes generating that token by setting the  
'safe_headers' option.  e.g. add this to your configuration file:

[Headers]
safe_headers:abuse-reports-to,date,errors-to,from,importance,in-reply- 
to,message-id,mime-version,organization,received,return- 
path,subject,to,user-agent,x-abuse-info,x-complaints-to,x-face

(That's all the defaults, except for reply-to.  Note that it should  
be all one line).
