Ubuntu – Connection refused by AMAVISD-NEW

I found here many information to set a AWS server on my own.

I installed the DKIM patch and it's work great, but now I can't send mails.
I had already problems sending mails, but now are deeper.
Some mails was sent and I tested my DKIM sign, but now I don't know what happened…

ISPConfig version is 3.0.5.4p9 with Ubuntu 14.04.4 LTS

You can see mail.log here:

I already read many tutorials and forums with the same problem but I still stopped on that.

Obviously the problem is "warning: connect to transport private/amavis: Connection refused"

I have the same results from Thunderbird and SquirrelMail.
The process completed succesfully, without errors, but the e.mail never leaves the queue
