Package: exim4-config Version: 4.84-8 Severity: wishlist Dear Maintainer,
please add some options to pin the smarthost certificates. This patch adds REMOTE_SMTP_REQUIRE_TLS to prevent smtp-transport to fall back to unencryptet transport if TLS failes for some reason REMOTE_SMTP_SMARTHOST_REQUIRE_TLS to prevent smtp-smarthost-transport to fall back to unencryptet transport if TLS failes for some reason REMOTE_SMTP_SMARTHOST_VERIFY_CERTIFICATES to allow the smarthost-certificate given in a file instead of using system-defaults --------------------------------------------------------------------------- diff -Naur etc/exim4/conf.d/transport/30_exim4-config_remote_smtp /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp --- etc/exim4/conf.d/transport/30_exim4-config_remote_smtp 2014-07-22 19:16:03.000000000 +0200 +++ /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp 2015-03-08 15:36:54.496189291 +0100 @@ -45,3 +45,7 @@ .ifdef REMOTE_SMTP_PRIVATEKEY tls_privatekey = REMOTE_SMTP_PRIVATEKEY .endif +.ifdef REMOTE_SMTP_REQUIRE_TLS +hosts_require_tls = REMOTE_SMTP_REQUIRE_TLS +.endif + diff -Naur etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost --- etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost 2014-07-22 19:16:03.000000000 +0200 +++ /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost 2015-03-08 15:51:48.599668544 +0100 @@ -36,3 +36,9 @@ .ifdef REMOTE_SMTP_SMARTHOST_PRIVATEKEY tls_privatekey = REMOTE_SMTP_SMARTHOST_PRIVATEKEY .endif +.ifdef REMOTE_SMTP_SMARTHOST_REQUIRE_TLS +hosts_require_tls = REMOTE_SMTP_SMARTHOST_REQUIRE_TLS +.endif +.ifdef REMOTE_SMTP_SMARTHOST_VERIFY_CERTIFICATES +tls_verify_certificates = REMOTE_SMTP_SMARTHOST_VERIFY_CERTIFICATES +.endif --------------------------------------------------------------------------- -- Package-specific info: Exim version 4.84 #3 built 17-Feb-2015 17:45:49 Copyright (c) University of Cambridge, 1995 - 2014 (c) The Exim Maintainers and contributors in ACKNOWLEDGMENTS file, 2007 - 2014 Berkeley DB: Berkeley DB 5.3.28: (September 9, 2013) Support for: crypteq iconv() IPv6 GnuTLS move_frozen_messages DKIM PRDR OCSP Lookups (built-in): lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmjz dbmnz dnsdb dsearch nis nis0 passwd Authenticators: cram_md5 plaintext Routers: accept dnslookup ipliteral manualroute queryprogram redirect Transports: appendfile/maildir/mailstore autoreply lmtp pipe smtp Fixed never_users: 0 Size of off_t: 8 Configuration file is /var/lib/exim4/config.autogenerated # /etc/exim4/update-exim4.conf.conf # # Edit this file and /etc/mailname by hand and execute update-exim4.conf # yourself or use 'dpkg-reconfigure exim4-config' # # Please note that this is _not_ a dpkg-conffile and that automatic changes # to this file might happen.
