Bug#1062357: systemd-cron: broken result mailing implementation

[Martin-Éric Racine]

Package: systemd-cron
Version: 2.3.0-1~bpo12+1
Severity: important

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

1) In its current form, systemd-cron mails the result of global cron jobs from root at fqdn, which fails since we aren't FQDN's administrator.

2) As a result, systemd-cron tries to notify the administrator of the failed delivery, but does so from a non-existent mail account _cron-failure, which thus also fails.

Fixing this requires systemd-cron to support the SENDFROM variable.
