Field "Resent-From"

Firstly to salute to all the members of the list. Sorry if my english is so bad... I have a problem with SmartList: when a user send an email to the list, in head of message appears all the suscriptor's directions in the field "Resent-From"; this it's very annoying when the suscritor's number is so long. How i'll can remove this field of the all message's header? Salu2 -- wikier@asturlinux.org http://www.wikier.tk wikier@jabber.org
