Hey Steffen, thanks for the quick response! I enabled auth-debug now in dovecot.
A normal telnet ip 143 works, after I put disable_plaintext_auth to no of course. I could connect, and see my folders. Mail.log didn't give me anything abnormal, and showed me neatly the connection and the sql querries. One abnormality though, just mentioning it, when I try to type in 1 login user password, I got a "BAD Error in IMAP command received by server." Or when I copy pasted the same thing (from the localhost terminal where I tried it there) it worked.
After that I tried gnutls-cli -p 143 --starttls localhost 1 STARTTLS ^D
It gave me following error: The hostname in the certificate does NOT match 'localhost' It's probably a certificate error (I use a self-signed, planning on buying one maybe later). I'm now digging google again, and triple checking each conf file. I added the hostname to the localhost entry of /etc/hosts, but no positive response yet.
Thank you again Greetings, Thomas Standaert

Did you enabled auth_debug in Dovecot ? When you use
telnet ip 143 1 login "user" "password"
does it work? MUAs do too much, when it does not work at once.
It it works, try using TLS e.g.:
gnutls-cli -p 143 --starttls localhost STARTTLS ^D 1 login "user" "password"
