Why is it a bad idea to use customer email as from address

I’ve got an application that emails users once they have filled in a form. It uses a no-reply@customerdomain.com as a from address.

I feel really vague about the exact reason about why this is a bad idea particularly as i’ve got […]

I need to change the DNSs of my domain, and I’m getting an error that the DNSs aren’t registered. Maybe they simply haven’t propogated yet, but it ocurred to me that what I’m doing seems kind of recursive.

And in case you’re wondering, I didn’t […]

Raise domain function level

I have a domain with Win2012 DC’s, and a bunch of Win2003 servers. Is it save to raise the functional level of the forest and domain to Windows 2012? Asked by Michelle Yes. Member servers don’t typically care what the FFL and DFL is – only domain controllers. As long as all your DCs are 2012, then go for it. And you don’t have a bunch of other stuff that you’re not telling us like […]

Name Servers with Registrar vs. Host Provider

This may be a redundant questions, but is there any benefit to using name servers with a registar provider vs. a hosting provider?
