It seems mutt outputs nothing to stderr but everything to stdout :-/ What makes the output a bit less messier is to call: env TERM=dumb mutt ... But I think I should try to use another tool, to achieve what I want, does anybody know a perl module to extract some data from Mails and to move mails from Maildirs to mboxes? (Any other tool to achieve this would be welcome, too) Nicolas
