If I understand this right, than all traffic is routed VIA this proxy.
Right ?
Which mean, if the proxy is located in e.g. Morocco and there is a
local network in France ($USER + Mailbox-Server) the request and
the traffic goes via the proxy in Morocco?
It is not a simpel redirect/hint where the Mailbox-Server is to find?
If this is right, it will be better for the Clients (and my Setup)
if the clints connect directly to there Mailbox-Server. Right?
So the Flow-Diagram will be for receiving Messages:
postgresql
|
|for the Mailbox-Server lookup
someone sends |
Message from ---->---- mx.domain.tld ---->---- mbox-ma.domain.tld
the World which is in Morocco
and geting Messages from IMAP/POP via proxy
postgresql
|
|for the Mailbox-Server lookup
|
$USER +---->------- mx.domain.tld ----->---+
in / in \ mbox-fr.domain.tld
France +----<-----+ Morocco +---<---+ in France
and for geting messages without proxy
$USER +--->--- mbox-ma.domain.tld
Another person had told me that it would be better if I use an
ISP in Euro for the Mailservices but I do not know, because my
$USER will increase and I do not like to put 1.000.000 $USER
or more in the Hand of an external ISP.
I think, if I have more then 60.000 $USER, than it is required
to use a cluster of MailServers, because Security and Performance.
