[SOLVED] postfix/dovecot don't send emails [outside and locally]

Told you I don't use ubuntu ao I too have to do my search.
So try the following to see if you have already installed the latest version:

Code:

apt-cache policy postfix

And once again:
Before anything else, why don't you use in master.cf the following:

Code:

lmtp : "lmtp unix - - y - - lmtp

I've checked the lmtp and it's alredy like that.

I even run the apt-cache command and I got

Code:

apt-cache policy postfix
postfix:
  Installed: 3.1.4-4ubuntu1
  Candidate: 3.1.4-4ubuntu1
  Version table:
 *** 3.1.4-4ubuntu1 500
        500 http://it.archive.ubuntu.com/ubuntu zesty-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     3.1.4-4 500
        500 http://it.archive.ubuntu.com/ubuntu zesty/main amd64 Packages
     3.1.4-3 500
        500 http://ppa.launchpad.net/lamont/postfix/ubuntu zesty/main amd64 Packages

So I think the version installed is already the updated one so I really don't know where the problem is.

Try to send an email from an external provider while watching the logs and see what happens.

Finally I solved my issue, the problem was that for some strange reason the port 25 was not open.
Now works everything good!

thanks for your support anyway I learn some other few things trying to solve my issue, have a nice week end

unfortunately the logs information were not available because the client couldn't reach dovecot but I discovered that the bounced email on the very bottom had some very useful information that indicate me that the problem were not on the IMAP but on SMTP!!
Very strange!
