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. > lg, > daniel Greetings Michelle -- Linux-User #280138 with the Linux Counter, http://counter.li.org/ Michelle Konzack Apt. 917 ICQ #328449886 50, rue de Soultz MSM LinuxMichi 0033/3/88452356 67100 Strasbourg/France IRC #Debian (irc.icq.com)
