jobs.netは安全ですか？

Owned by CareerBuilder, LLC; same owner of *****. See: http://who.is/whois/jobs.net By providing an email address to *****, you will receive no automated notification of opt-in to email from jobs.net routed through ***** Email header at least sometimes originates from a Careerbuilder LLC IP address, example 208.82.x.x or 208.88.x.x.x See: ***** (Careerbuilder LLC owned IP network ranges) ***** (currently green) ***** (currently green) AND I found no notification on the workinretail.com website, that an email would come come from "jobs.net" or be routed through "sendgrid.net". Spam by obscurity. If jobsnet / Careerbuilder LLC wants a green rating from me, have a new policy requirement for senders like workinretail.com to post a notification that "jobs.net" will be used.
