Here is the relevant part of dovecot config :
service stats { unix_listener stats-reader { user = $default_internal_user group = $default_internal_user mode = 0660 }
unix_listener stats-writer { user = $default_internal_user group = $default_internal_user mode = 0660 } }
All other mails get in without problem. I suspect it gets in, then confuses the mail system because of proxy:unix:passwd.byname in postfix config local_recipient_maps
I don't need this btw.
