Bug#817244: exim4-base: cron noise re environment

[Matthew Vernon]

Package: exim4-base
Version: 4.86.2-2
Severity: normal

Hi,

I now (last few days) get an irritating email every day from anacron,
thus:

/etc/cron.daily/exim4-base:
LOG: MAIN
  WARNING: purging the environment.
 Suggested action: use keep_environment and add_environment.

This is pretty tiresome!

Thanks,

Matthew
