Hello,

If there are two or more addresses set in the "Reply-To Address" (separated by a comma), then builds fail due to the following error (I would like to be able to have more than one email specified as there are more than one person managing Jenkins):

ERROR: Unable to send to address: fxxxxxxh@cxxxxxxt.com,CxxxxxxK@hxxxxxxxxs.com
