Hi, I have a bunch of jessie hosts that are all very similar, and since this upgrade one of them has been sending me this cron email during cron.daily.
I checked out the difference between that host and the other and the only difference in /etc/exim4/update-exim4.conf.conf was: dc_use_split_config='false' After reconfiguring to use single config file I do not receive the warning. As I say these are very simple systems. Full content of /etc/exim4/update-exim4.conf.conf on them all (now) is: dc_eximconfig_configtype='internet' dc_other_hostnames='theirhostname.localnet' dc_local_interfaces='127.0.0.1 ; ::1 ; 192.168.80.19' dc_readhost='' dc_relay_domains='' dc_minimaldns='false' dc_relay_nets='' dc_smarthost='' CFILEMODE='644' dc_use_split_config='true' dc_hide_mailname='' dc_mailname_in_oh='true' dc_localdelivery='maildir_home' Cheers, Andy
