Re: That is what REPLY-TO/reply address is for

said by keith2468 See Profile:
That is what the REPLY-TO (in OE accounts, the "reply address") is for.

SENT-BY (FROM or, in OE accounts, the "email address") is formally supposed to be the email address on the ISP the computer is actually on.
Says who?

This premise cannot possibly hold water, and it's hard to even know where to start.

First, and most broadly, your online identity is anything you want it to be, and in my book, you "are" any email address to which you have valid access to the mailbox. This gives me probably a half a dozen email addresses, none of which is the "real" address unless I say one of them is.

Second, many people purchase IP services with the sole intent of routing IP packets, and they do not buy into the additional services (email, web space, home page) that the ISP may offer. I have Pac*Bell DSL, but as far as I know I don't have a @pacbell.net email address.

Finally, there is no required connection between "email address" and "physical location" - otherwise this premise would play havoc with the salesman on the road: does he get a new "Sent-From" email address in every hotel?
