I have a site hosted on GoDaddy, and one of the sections uses cron jobs called by webbasedcron.com . I coded it so that every job sends me an email when it starts, and when it finishes. This means 6 emails right after midnight, and 2 every other hour of the day.
The strange thing is that I occasionally get the following bounce emails from Secureserver (the company that takes care of GoDaddy SMTP):
Hi. This is the qmail-send program at p3nlsmtp02.shr.prod.phx3.secureserver.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<casherryw@co.jefferson.tx.us>:
71.40.211.75 does not like recipient.
Remote host said: 550 Requested action not taken: mailbox unavailable
Giving up on 71.40.211.75.
<wishardbdd@calhoun.k12.mo.us>:
150.199.98.149 failed after I sent the message.

Since the emails are set to be sent ONLY to me, why do I get bounce emails with these strange addresses listed? Is this some kind of phising/spam attempt?
