Re: Cancelled Verizon DSL, Lost All Emails
It sounds to me that he was using, perhaps unknowingly, a "relay personality". This is a feature of some email clients that will route outbound mail transparently through an ISP's smtp server, while preserving the appearance that it actually came from somewhere else. In some cases this kind of thing is necessary because some ISPs block port 25 in an attempt to thwart the use of spambots on their users. With port 25 blocked most clients can't access outbound relays other than those belonging to the ISP. (FYI, in reality there are workarounds sometimes. Many SMTP relays will accept outbound mail on port 591 and that's never blocked in my experience.)
So what might have happened was that your friend may have been sending mail through VZ's server without realizing it, and the mail client was authenticating as always, without drawing attention to what it was doing. Then, when the account was closed, the authentication failed and the client threw up its hands and said "I don't know how to send this mail any more".
As far as the existing mails vanishing, I can't help you. But making an inference from your description of events, I'd suspect that they're still there, but the client doesn't know how to access them since the account was deleted. If I were faced with the assignment of finding them, I'd try recreating the account identically (you shouldn't need to login to VZ's servers to do that) to the way it was and see if they don't reappear. |

| said by srr2  :Many SMTP relays will accept outbound mail on port 591 and that's never blocked in my experience.) RFC 2476 defines port 587 for message submission. I know a few servers (smtp.gmail.com, smtp.gmx.com, smtpauth.sbcglobal.net) which use port 587. Don't know of a single server using port 591 (though there is no reason why a server administrator couldn't use; other than it not being defined in a standard).
