When i send email from hotmail, gmail o any other corporate domain i cant recieve email, but if i disable the firewall i able to recieve.
What is missconfigurated on the firewall that restricts incoming mails?

Because of spammers, yahoo, hotmail and others often block domains and some attachments.
Or it might be that your firewall might be blocking the emails due to Brute Force attack.

CSF per se does not block emails; CSF only block IPs and ports.
So, check your configuration and check if SMTP ports are open you will like to have the following
SMTP_PORTS = 25,465,587
remember that you have to open those ports where it needs in TCP/UPD IN/OUT.
