Hi, I have same problem with fresh install on Centos 7 VPS.
There are two errors in script sentora_postfix.sql:
1. in table quota engine is set MyISAM and for keys bigger than 1000 bytes just use Engine=InnoDB
2. in table vacation_notification there is foreign key on col on_vacation to table vacation (email). But email is defined as utf8 varchar and on_vacation is latin1 varchar which leads to error
#1005 - Can't create table 'sentora_postfix.vacation_notification' (errno: 150)
