I've a server that uses Qmail. It is installed by default and it is supposed to work. I've created a new domain and new user (vadddomain + vadduser) without problems, but when I send an email from Gmail to firstname.lastname@example.org (the address I've created) it desappears, it is. But if connect to SMTP server directly (telnet domain.com 25) and post an email it arrives to the user queue. What's happening?!?
Note: If I try to access to my user through telnet domain.com 110 it seems my pwd is not correct and it's the same I used when created the user with vadduser
