@fredmosc I found your Problem :-) look :

smtpd[21418]: connect from host1.hdvida.com.br[192.161.241.202]
Aug 27 13:17:17 odin postfix/smtps/smtpd[21193]: SSL_accept error from hm2256-2.locaweb.com.br[187.45.217.68]: Connection timed out

The first “problem” (for me) is you have not a logical Postfix Configuration (no order).

The second real problem is you have a weak TSL configuration

Here for e.g. my configuration:

##### TLS settings ######

tls_preempt_cipherlist = yes
tls_ssl_options = NO_COMPRESSION
tls_high_cipherlist=EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
smtpd_tls_dh1024_param_file = /etc/nginx/ssl/dhmail.pem

### outgoing connections ###
smtp_tls_security_level=may
smtp_tls_cert_file=/etc/nginx/ssl/mail.crt
smtp_tls_key_file=/etc/nginx/ssl/ssl.key
smtp_tls_ciphers=high
smtp_tls_protocols=!SSLv2,!SSLv3

### incoming connections ###
smtpd_tls_security_level=may
smtpd_tls_cert_file=/etc/nginx/ssl/mail.crt
smtpd_tls_key_file=/etc/nginx/ssl/ssl.key
smtpd_tls_ciphers=high
smtpd_tls_protocols=!SSLv2,!SSLv3

Please order and clean your configuration

nano /etc/postfix/master.cf and uncomment (remove the hashtag) #smtps inet n - - - - smtpd

Restart Postfix sudo service restart postfix
