[fetchmail]fetchmail's 'Received' header

Hi,

I like sorting my e-mails by the date of their reception on the server :
this date is obtained by taking the last "Received" header in the
e-mail.

I use procmail as MDA, so that my local MTA does not add a Received
header. The problem is the one added by fetchmail. Is there a way to
prevent fetchmail from adding it ?


thanks,
