No Content-Type headers in emails from Anacron

[Gavin Chappell]

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.
