Symbiosis: Exim "Warning: purging the environment" error on restart
Imported from https://www.github.com/BytemarkHosting/symbiosis/issues/114
Exim prints the following warning message whenever the service is restarted:
Jun 18 14:12:19 symbiosis2.default.aladlow.uk0.bigv.io exim4[573]: Starting MTA:2018-06-18 14:12:19 Warning: purging the environment.
Jun 18 14:12:19 symbiosis2.default.aladlow.uk0.bigv.io exim4[573]: Suggested action: use keep_environment.
This message is fairly harmless but can cause emails to be generated from cron.daily
, for example:
/etc/cron.daily/exim4-base:
LOG: MAIN
Warning: purging the environment.
Suggested action: use keep_environment.
The solution should be to set keep_environment =
in Exim's configuration.
