Ok. My /etc/exim/exim.conf has: local_delivery: driver = appendfile group = mail mode = 0660 mode_fail_narrower = false envelope_to_add = true return_path_add = true file = /var/spool/mail/${local_part}but mutt tells me that /var/spool/mail/paul is not a mailbox.
BTW the way where is local_part defined? Thanks for any more help, Paul
