After roughly 6 hours of searching i decided to ask help here
I've tryied setting up postfix, everything worked great
Then I've decided to use my emails on thunderbolt, which didn't work
So i figured out that i had to setup a SASL auth, so I did (Or at least, i think I've set it up as telnet replies with "AUTH PLAIN")
Okay, now that you have a general idea, there are my configs:
/etc/postfix/main.cf
smtpd_banner = $myhostname ESMTP $mail_name
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.

As you can see, I'm unable to login.
How is this possible? Could someone help me or anything?
Thanks in advance, and have a nice day!
EDIT:
I've edited the Telnet output to explain better what i did, and when I'm talking about thunderbird, "Didn't work" means this:
[Thunderbird settings][1]
[Used user][2]
P.S: Please don't downvote this question, I've really searched everything that I could, and after 6/7 hours I gave up and tryied to ask here. Be nice please, this is the first time I've ever used postfix
With those settings, thunderbird still says that it can't find the settings for my email account.
