Package: cron Version: 3.0pl1-124 Severity: normal cron sends 8-bit messages that are lacking a MIME-Version header. This is in violation of RFC 5321 ยง 2.3.1:
The content is textual in nature, expressed using the US-ASCII
repertoire [6]. Although SMTP extensions (such as "8BITMIME", RFC
1652 [22]) may relax this restriction for the content body, the
content header fields are always encoded using the US-ASCII
repertoire.
Because I have configured Postfix to reject invalid 8-bit data, certain
cron mails are not delivered. If cron is going to send 8-bit data, it
must do so only as part of a valid MIME message meeting the requirements
of the 8BITMIME specification. Also, the Content-Type header included
is completely meaningless outside the context of MIME.
Included below are the headers from the mail:
