Sorry, not sure I fully understand your point..

assuming that Ive installed and configured a Local SMTP server (as described in product blurb url) for outbound mail using Outlook Epress or Microsoft Mal ,

Are you saying that a Local SMTP server (which would bypass the ISP SMTP server) would normally generate a 480 error ?

the product desciption seem to indicate that Local SMTP relay server is designed specifically to avoid using the ISP mail server !

Presumably if its your local SMTP relay server then 550 authorisation errors would not be an issue ?

PS one the options Im looking at is http://www.getfreefile.com/localsrv.html

Im trying to understand if SMTP relay is a solution looking for a problem

As I understand it, the protocol SMTP is needed to "talk" to the target mail exchange

This is normally done via a SMTP relay server which accepts outgoing requests from a number of clients and routes them onward

However as it is possible to buy Local SMTP relay on the client which will send messages DIRECTLY to the target mail exchange

Can any one suggest reasons (url) why Local SMTP relay is not standard ?

It seems to avoid sending mail via third party servers and the associated security pitfalls


PS I guess the problem may be my understanding of DIRECTLY (client to target mail exchange)

Could depend on what kind of authorization they require, but those generally produce a 480 server error I've almost never seen one caused by anything but trying to use an SMTP server other than the one belonging to the ISP to which you are connected.

No, I left 550 out of the last sentence.
Usually:
480 = authentication error.
550 = port 25 blocking.
