X-Mailer: ZuckMail [version 1.00]

I mean is this custom-made smtp mailer? or X-Mailer header with custom value like X-Mailer:myMailer ?

You can set the X-Mailer header to anything you want so it was probably the script developers pet name. In this case I would guess it is an email from Facebook with Zuck being short for Mark Zuckerberg.
