* Switch to stretch-slim as base image. - first step correct the testdata, as newer packages are more strict about the mail-structure. * Switch to stretch-slim: correcting the test-environment and the build - add missing build-step to make - clean the userdb aswell - use timeout of netcat, as postgrey would not close the connection - there is 2 extra mail-logs -> assert_output 5 - cosmetic: use "" instead of '' * Switch to stretch-slim: new image: - smaller size - 0 CVEs compared to 11 CVEs in ubuntu 16.04 Image better backport situation - postfix 3.1.6 vs 3.1.0 - fail2ban 0.9.6 vs 0.9.3 ... changes needed because of stretch-slim: - add missing gnupg and iproute2 package - remove non-free rar, unrar-free should do - rsyslog does not add syslog user and has different conf-structure - pyzor command discover was deprecated and is missing in the new stretch package - dovecot does not know SSLv2 anymore. removed because of warnings in log - iptables does not know imap3, IMAP working group chose imap2 in favor of imap3 * Switch to debian stretch slim: SSLv2 seems to be a not known protocol anymore - good! * switch to debian stretch slim: make this test more stable. there might be more than only one mail.log (mail.info, mail.warn, ...) * switch to debian stretc slim: new openssl 1.1.0 needs stronger ciphers, removed some weekers ones. Please, look through the new list of cipher! this needs to be done in another commit for all other SSL/TLS-Endpoints aswell. * Switch to debian stretch slim: let our server pre-empt the cipher list. Did a read through, wwwDOTpostfixDOTorg/FORWARD_SECRECY_READMEDOThtml and wwwDOTpostfixDOTorg/TLS_READMEDOThtml * Switch to debian stretch slim: lets give this openssl-based test a new and independent but identical container. many other test on the main 'mail' container might interfere here. * Switch to debian stretch slim: remove unused lines
