Topic: Failure to receive from and sent to external email

Debian Jessie, 8.2
MariaDB
Nginx
Virtual Box 4.3.28

I am able to send / receive email between internal example.org user accounts; but from / to external email is failing.
See mail log attached. _NOTE_: mail FROM domain has been replaced with example.org and TO domain with XXX.example2.org.

Thank you

Re: Failure to receive from and sent to external email

Next time, please extract related log and paste in your post directly, do not simply throw out a log file and ask others to dig for you. Save others' time.

Your server cannot connect to Google mail server at all, please check your network configuration, and make sure your network can reach (e.g. telnet) other servers.
