I'm using a internal Mail server without any Sécurity connexion but with a authentication method "crypted password"

I can't manage to connect to my server as it look slike Projeqtor is trying to connect it using TLS/SSL security method .
How can I configure PQt to use a 'simple mail server' without security ?

Thanks for your help

here is a log view, i just xxxx adress
