mysteriously receiving emails sent from cakephp on localhost months ago
Today I received around 20 emails in total over the course of about 3 hours.  The emails are from 5 different websites that I developed that are now each hosted with different companies.  It seems that these are all emails that were generated during the initial development of each site, which was all done in a localhost environment (not configured to send out email).  I cannot figure out why I am getting these messages months later.

Here is the raw source of one of the emails:
