No not e-mail, but as in a fully valid e-mail address

From: rusty{at}mango.zw
To: Kai Richter

Precisely ...

The originating system is an NGO, which due to many years of operating in 
isolation, has evolved a non-standard addressing system, and also supplies 
e-mail to it's members. Sending mail to me is not a problem, but sending 
echomail onward from this system in the form it arrives here, is where it 
starts ...

 KR> That is why i don't understand your wish.
 KR> You want to avoid something that had already happend.

Unfortunately yes, and due to that fact, very difficult to change at this 
stage ...

 KR> And you want a reverse translation for outging mail.
 KR> The result is that there are no changes for the outside world.


Basically, I would like to be able to substitute Russell Tiedt, for 
rusty{at}mango.zw on out going mail and reverse that for each user of the system 
for the replies. This for a limited know set of users, I know I can do 
somewhat similar with sendmail, but I am not using/running a e-mail system, 
but a fidonet system.

From: rusty{at}mango.zw
To: Kai Richter

So when the above example leaves here it will be;

From: Russell Tiedt
To: Kai Richter

When it returns here, from normal FidoNet space;

From: Kai Richter
To: Russell Tiedt

When the reply passes thru my system to system of origination, the reverse 
substitution takes place, resulting in:

From: Kai Richter
To: rusty{at}mango.zw

Russell Tiedt = rusty{at}mango.zw
Mike Savvas = mikes{at}mango.zw
Japie Erasmus = erasmusj{at}mango.zw

No - see above, hopefully that explains the situation ...

 RT>>>> and then when return mail/replies arrive, change the user name
 RT>>>> back to "rtiedt{at}mango.zw"

 KR>>> "change back", then that user name is correct? If
yes, you are
 KR>>> manipulating "in transit" mail and you put a time
bomb into your
 KR>>> msgbase.

 RT>> The msgbase is none the wiser ... , this has to be done before

 KR> The only result is that you hide your real address to all users of
 KR> your msgbase. Is that what you want to do?

I want to protect their e-mail address, by substituting their real names for 
their e-mail address ...

 KR> Are you sharing your msgbase?

Sharing as in more than myself directly accessing the msg base, no, I am not 
...

Sharing as in exchanging echomail with other systems, yes ...

 RT>>>> when outgoing packets to node are scaned out?
 RT>>>> This is for multi-user usage, not just for a single user ...

 KR> Your msgbase is used for multi-user usage?
 KR> Friends and family? Or open to the world?
 KR> (you said to the world at the top of this mail)

Multi-user = a node and all points of that system ... , that connect to 
FidoNet thru my system.

Not multi-user as in family/friends and is not open to world, only to FidoNet 
world

Hopefully the situation is a little clearer.

Regards,

Russell
