Hi...
i have the seing problem this my history i hope this help u a little..
First i think that u can only send Mail from Sentora (correctly) using a Static IP, it means, having a VPS or dedicated internet conection with Static/Fixed IP.
If you are trying Sentora from your home internet (it's my case) connection with Dinamyc IP (changes when the router reboot for example), you will no able to send mails to outside (gmail, hotmail an any other mail servers out ou your Sentora Server), only in your self Sentora server.
WHY??. #####################################
In don't known xD, there are to much requisites to setup a working SMTP server on Sentora.
First place (its my case) the damn 25 port, all the time a get this on my mail.log:
Mar 18 21:42:57 ordenazteca postfix/smtp[3217]: connect to mx3.hotmail.com[65.55.37.104]:25: Connection timed out
because my ISP (i'm testing on my home), has blocked port 25 (i guess).
I has tried change the port 25 on the master.cf adding 587(submission) and 465(smtps):
smtp inet n - n - - smtpd
smtps inet n - - - - smtpd
submission inet n - n - - smtpd
but postfix still sending from 25 port:
Mar 18 21:42:57 ordenazteca postfix/smtp[3217]: connect to mx3.hotmail.com[65.55.37.104]:25: Connection timed out
SO, WHAT NEXT??. #####################################
I has tried use Gmail like relayhost, this WORKS fine BUT NO SOLVE THE PROBLEM, because when the mail arrives to the destinatary, the sending email account that appears is the gmail account, not the accout of your domain hosted in your Sentora Server.
If you whant to try relay host check this tutorial, i used it today to the relay config:

It's my experience moment, so i'm a noob on this, hope somebody more experiment can help you.
Sorry for my bad english (no google traslated xD), grettings from México City, ciao.
