After installed Zabbix 2.4.7 I cannot received email from zabbix, and I checked /var/log/maillog found lot error like this:

Then I checked postfix status, postfix can't start.
[root@localhost ~]# postfix status

I also tried to link libmysqlclient.so.18 to libmysqlclient.so.16, problem did't solved.
