<color><param>0100,0100,0100</param>Hello Philip. Thank you for the reply.


I have attatched the relevant debug info, but here is a more useful english
explanation.


You have an account with us. I allow you to send out and receive mail
through my box; but the service being used is actually a transparent
rewriting of YOUR address - You appear as one of my local users, as do
all the users you are mailing to through my machine. The benefits are that
firstly, you do not have to tamper with any of the settings in your mail
client, and secondly you are granted a pseudo-anonymous email account.


Hence, in my abortive attempt, I firstly (assuming that the headers are
rewritten in the order which they are specified, which I now don't think they
are) tried to rewrite the senders address from a remote address to a
local_part (through lsearch /tmp/aliases) Ffrs

and finally completed the process by rewriting the envelope_To: (which
works as expected).


Mississippi pie? ;-)


Am currently trying to see if a director with headers_remove, <FontFamily><param>Times New Roman</param><bigger>or a
transport using headers_rewrite will do what I want.<FontFamily><param>Arial</param><smaller>


Regards,


    Phil
