BTW... this is one of the best HOWTOs website I've ever come across. Two thumbs up. Anyway, I have completed the 'The Perfect Setup - Debian Woody' and what do I need to do in order to send mails from my XP machines (outlook) to my Debian server and let the Debian server deliver the mail to my ISP? I have three XP machines in the network and the forth one is the Debian server (192.168.0.3). All is connected through a router (broadband). My ISP's (NTLWorld) smtp/pop3 servers are: smtp.ntlworld.com pop.ntlworld.com To send mail I have to use SMTP authentication. For example, if my email address is email@example.com does that means I have to create an account on the Debian server as john.doe?
