Postfix PCI Compilance in Zimbra Collaboration
- This article is a Work in Progress, and may be unfinished or missing sections.
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,\!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.
