Bug#794320: main option "prdr_enable" unknown

[Andrey Rahmatullin]

Package: exim4-config
Version: 4.86-1
Severity: serious

After updating an old testing system I get this:

Setting up exim4-config (4.86-1) ...
2015-08-01 15:04:52 Exim configuration error in line 140 of
/var/lib/exim4/config.autogenerated.tmp:
  main option "prdr_enable" unknown
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing
/var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated
dpkg: error processing package exim4-config (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 exim4-config


prdr_enable is indeed contained in
/etc/exim4/conf.d/main/02_exim4-config_options
