The thing that happens is, I create a new unique address for a business I'm dealing with. I put the company's name in the local-part of the email address I give them (that's the part before the "@" symbol in an email address).
And then they contact me demanding to know why (or how) I'm using "their" email. They see their company name or domain name in the local-part of my address and get incensed, thinking it's impossible, or illegal even. It makes no sense; would the greeting card mafia have a case against a big webmail provider if one of their users created the "hallmark@BigWebmailProviderDomain" address?
On more than one occasion, I have picked up the phone to find someone YELLING at me about "hacking their server" because of this.
I spend some time explaining it to them. Half the time, they kinda/sorta get it and calm down. The other half refuse to even stop yelling and think about what I'm telling them.
And this isn't some random one-person business I'm dealing with. Today, it was *my bank* that called me to demand to know why my support request email address had "their email" in it.
You would hope a bank, operating an online banking site, would have staff that have at least a passing familiarly with email and the internet. But nope.
To make it worse, this is actually the second time my bank has gotten upset about it.
