This depends of a new package to made in debian: Courier Socks 5 Proxy client library, which allows Courier to send outgoing mail using a Socks 5 proxy.
This means need to convert or merge this bug request in a RFP of the Courier Socks 5 proxy before building Courier in order to use a Socks proxy to send outgoing mail. FEATURES: 1. Courier-mta is the only suite that can use a socks5 to delivery to a different network 2. Access control: define IP address ranges allowed to proxy through the server. 3. Access control: import list of banned IP address range, in the P2P file format. A "socksify" application wrapper script, that uses shared library tricks to try to redirect network connections from standalone application through the Socks 5 proxy server. http://www.courier-mta.org/download.html#sox Lenz McKAY Gerardo (PICCORO) http://qgqlochekone.blogspot.com
