This article applies to the following ZCS versions.

Reconfigure the Postfix SSL/TLS settings

Configuring Postfix for PCI Compliance

Reference - http://www.postfix.org/TLS_README.html

For ZCS 8.5, as the zimbra user

zmprov mcf zimbraMtaSmtpdTlsCiphers high
zmprov mcf zimbraMtaSmtpdTlsProtocols '\!SSLv2,\!SSLv3'
zmprov mcf zimbraMtaSmtpdTlsMandatoryCiphers high
zmprov mcf zimbraMtaSmtpdTlsExcludeCiphers 'aNULL,MD5,DES'

Within 2 minutes, zmconfigd will update postfix for you, and the system will be PCI compliant.

For ZCS 8.0 and previous, as the zimbra user

zmlocalconfig -e smtpd_tls_ciphers=high
postconf -e smtpd_tls_protocols=SSLv3,TLSv1,\!SSLv2
zmlocalconfig -e smtpd_tls_mandatory_ciphers=high
postconf -e smtpd_tls_exclude_ciphers=aNULL,MD5,DES

The SSL/TLS settings are now reconfigured. The changes will take effect within 2 minutes. Note that smtpd_tls_protocols and smtpd_tls_exclude_ciphers will need to be set after every upgrade as there is no way to preserve them in ZCS 8.0 and previous.
