[Bug 1313055] [NEW] No Content-Type headers in emails from Anacron

[Gavin Chappell]

Public bug reported:

I have some cron.daily jobs which output in UTF-8 (due to doing file
operations on /etc which contains some files with UTF-8 characters).
These are run through Anacron and emailed through the Mandrill mail
service. Because there's no Content-Type headers sent with these,
Mandrill accepts them as ISO-8859-1 by default. Part of the Mandrill
process is to break the mail apart and recreate it before sending to the
target email address, this process fails because of the UTF-8 characters
and the mail is truncated as soon as it hits the first character which
is outside of its expected character set (which is ISO-8859-1).

runjob.c seemingly has no method for specifying a Content-Type, and
although this can potentially be worked around by having the first line
of my shell scripts echo "Content-Type: plain/text; charset=UTF-8" this
breaks anacron's detection of whether there's any output (which compares
the file size of the temporary file containing the mail headers before
and after the job has run). This approach also isn't compatible with any
non-shell script jobs.
