net_connect_unix(/var/run/dovecot/stats-write r) failed: Permission denied

[Mike Clarke]

I'm getting the following error message in my exim log for every incoming message:

dovecot_delivery transport output: lda(mike,)Error: net_connect_unix(/var/run/dovecot/stats-write

It's not preventing messages getting to me but I wondering how I should deal with it.
