=?utf-8?b?cHJvYmzDqG1l?= de destinataire avec mutt

Bonjour,
J'ai un petit souci avec mutt. J'ai un script qui lance la commande suivante:
mutt -s "index" -moi@monserveur -a indexroot.csv -d 5

Quand je lance ce script en tant que root (nécessaire pour d'autre
partie du script), tout fonctionne, le mail part bien et arrive,
sachant que le mail ne reste pas en local, mais part via un FAI.

Si part contre la crontab exécute le script, le mail part sur
root@myhostname et pas sur moi@monserveur ci dessous les log de mail
et de mutt.

## *** DEFAULT SETTINGS FOR THE ATTACHMENTS PATCH ***
##

##
## Please see the manual (section "attachments") for detailed
## documentation of the "attachments" command.
##
## Removing a pattern from a list removes that pattern literally. It
## does not remove any type matching the pattern.
##
## attachments +A */.*
## attachments +A image/jpeg
## unattachments +A */.*
##
## This leaves "attached" image/jpeg files on the allowed attachments
## list. It does not remove all items, as you might expect, because the
## second */.* is not a matching expression at this time.
##
## Remember: "unattachments" only undoes what "attachments" has done!
## It does not trigger any matching on actual messages.

## Qualify any MIME part with an "attachment" disposition, EXCEPT for
## text/x-vcard and application/pgp parts. (PGP parts are already known
## to mutt, and can be searched for with ~g, ~G, and ~k.)
##
## I've added x-pkcs7 to this, since it functions (for S/MIME)
## analogously to PGP signature attachments. S/MIME isn't supported
## in a stock mutt build, but we can still treat it specially here.
##
attachments +A */.*
attachments -A text/x-vcard application/pgp.*
attachments -A application/x-pkcs7-.*

## Discount all MIME parts with an "inline" disposition, unless they're
## text/plain. (Why inline a text/plain part unless it's external to the
## message flow?)
##
attachments +I text/plain

## These two lines make Mutt qualify MIME containers. (So, for example,
## a message/rfc822 forward will count as an attachment.) The first
## line is unnecessary if you already have "attach-allow */.*", of
## course. These are off by default! The MIME elements contained
## within a message/* or multipart/* are still examined, even if the
## containers themselves don't qualify.
##
#attachments +A message/.* multipart/.*
#attachments +I message/.* multipart/.*

## You probably don't really care to know about deleted attachments.

attachments -A message/external-body
attachments -I message/external-body

##
# See /usr/share/doc/mutt/README.Debian for details.

Merci d'avance pour les idées, je deviens chèvre :(
