 From the headers, it seems it is being bounced to root as a catchall 
for the server so is there an alias from that email address to local 
user roger? If not, the server could be shipping it out, so Simon's 
comment may well be correct.

Otherwise, possibly a mailbox problem, viz:
postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

HTH.
