I'm following this postfix guide and im stuck at Authentication (SASL) point. I did all as i should without problem, but still i can login to smtp without any login/password. Im doing
telnet 127.0.0.1 25 and i dont have to provide any password.
Whats more, my goal is to use SHA1 as password hash method in database. Im really confused right now. Im finding misleading posts that i should use TLS instead of SASL or use Dovecot etc.
What im doing wrong? I lost point of using SASL at all, dont understand this.
