I will keep this behaviour next time.
Anyway, but after trying and retrying, it seems that I need to place:
"smtp_sasl_mechanism_filter = plain"
By forcing the mechanism the system is now able to connect to te server and send the mail.
Thanks again, Luca

That advice is here: http://www.postfix.com/DEBUG_README.html#mail
Specific to your request:
1. You should be expansive rather than selective when posting logs. In this case you seem to have logged the whole SMTP chat, yet you only posted 2 lines. Earlier lines in this case would be critical to any analysis.
2. Do not make any changes to log lines except to obscure truly security-sensitive information like authentication tokens or private email addresses. Hostnames and IP addresses are almost never worth obscuring and can be critical to figuring out a problem. In this case, you even asked about host identity and naming issues that we could help you with if you had not falsified what little evidence you provided.
3. Including 'postconf -n' output is important because it shows all of the non-default configuration that Postfix actually uses. Citing a few settings without stating whether they came from main.cf or postconf output leaves open a broad range for conjecture and if you don't know how to correct your config, then your determination of what configuration is "relevant" is likely to be wrong.
Some wild guesses on your difficulty:
A. Your provider isn't offering an AUTH mechanism that your SASL config will use so there was no AUTH attempted, yet your provider requires it.
B. Some idiot between your server and your provider has put a Cisco PIX or ASA in your path and turned on its 'smtp fixup' misfeature.
C. There are errant/mismatched quotes and/or whitespace in your main.cf that results in a formally valid format that is not being parsed as you intend it to be.
D. The main.cf file that you *think* Postfix is using is not the one it *is* using, due to a misconfigured chroot.
My hunch is that there is about a 90% chance that your problem is caused by something else, but all of those unlikely possibilities could be eliminated (or confirmed) if you were to simply follow the instructions for seeking help here.
