[Cdash] cdash upgrade and no longer sending emails

[Clinton Stimpson]

Hi,

I recently upgraded to CDash 2.2.3 and I am no longer getting emails when 
submission breaks builds.  I checked my subscriptions and they appear fine as 
before.

In config.php, I changed 
$CDASH_LOG_LEVEL = LOG_INFO;

then checked my backup/cdash.log file and there is nothing in there, so it 
appears it isn't even attempting to send emails.

Are there any tips for debugging this or fixing it?

I also saw this thread with another user not getting emails, but don't see any 
resolution there.
