Comment (by karsten):

 Hmm, this doesn't work as expected.  Here's what I changed, compared to
 commit 0a2f917:

 Note that I added the appender to two loggers for testing purposes.  I
 would expect it to send me mail once per hour with the statistics.  Still,
 I don't receive anything.

 I also tried sending mail from the command line.  The following command
 succeeds and results in an actual email in my inbox:

 {{{
 metrics@sewerzowi:/srv/onionoo.torproject.org/onionoo$ echo "Test body." |
 mail -s "Test subject" karsten@xxxxxxxxxxxxxx
 }}}

 Not sure if this is an issue that sysadmins could fix, because sending
 mail apparently works.  Is there an easy way to debug this on the Java
 side?
