I am running exim 4.84_2 on Debian, now since a few weeks I get the following mails from anacron:
/etc/cron.daily/exim4-base:
LOG: MAIN
Warning: purging the environment.
Suggested action: use keep_environment.
I have added the following line to /etc/exim4/exim4.conf.template
:
keep_environment =
But when running update-exim4.conf
I get the following error:
2016-05-17 00:20:00 Exim configuration error in line 900 of /var/lib/exim4/config.autogenerated.tmp:
option "keep_environment" unknown
Any ideas?
