I've gone back to basics and resinstalled using the debian 3.1 guide. i've followed the postfix part to the letter and am now trying to send an email using smtp in thunderbird. i added a system user, set the password then set the thunderbird smtp user name as the same. it then asks for my password word and i enter it but it is rejected and asks for the password again. i want to test the user/password using telnet in the system but I don't know how to accomplish this. Am i using the right username/password (i.e. i just used adduser to create an account in root)? /etc/postfix/sasl/smtpd.conf reads pwcheck_method: saslauthd mech_list: plain login i'm getting really confused with all this and searching google only seems to make things worse as everyone has different methods to do it.
