From: Christian Kastner Date: Sat, 26 Dec 2015 19:04:25 +0100 Subject: Send proper 8-bit emails Cron sends 8-bit emails, so it needs to send these mails as 8BITMIME. This involves passing -B8BITMIME so that sendmail knows what kind of data to expect, as well as sending an appropriate MIME-Version and Content-Transfer-Encoding header. Without these changes, mail servers that reject non-MIME 8-bit emails will reject cron's messages. Fix provided by brian m. carlson .
