Jun 16 14:18:13 mail postfix/master: warning: /opt/zextras/common/libexec/smtp: bad command startup -- throttling

and even i can't edit main.cf, everytime edited the always back to original main.cf

I was unable to send message when I check "Reject unlisted sender". You can find this option under MTA -> Inbound flow and security.

I didn't find the solution, there is something wrong with post screen. 

Normally it should work when you set my network 127.0.0.1/8 XXX.XXX.XXX.XXX/32.

I have to investigate more in postfix configuration.

Besides there is an error in lines:

PGPASSWORD=DB_ADM_PWD carbonio-tasks-db-bootstrap carbonio_adm 127.0.0.1

should be in my opinion:
