From 09cd9f998780fb7179b7fc23c593c305a12b050a Mon Sep 17 00:00:00 2001 From: Guilhem Moulin Date: Thu, 6 Dec 2018 21:06:38 +0100 Subject: MX: chroot postscreen(8), smtpd(8) and cleanup(8) daemons. Unlike what we wrote in 2014 (cf. 4fb4be4d279dd94cab33fc778cfa318b93d6926f) the postscreen(8) server can run chrooted, meaning we can also chroot the smtpd(8), tlsproxy(8), dnsblog(8) and cleanup(8) daemons. --- .../MX/files/etc/postfix/reject-unknown-client-hostname.cf | 2 +- roles/MX/files/etc/postfix/virtual/alias.cf | 2 +- roles/MX/files/etc/postfix/virtual/alias_domains.cf | 2 +- roles/MX/files/etc/postfix/virtual/catchall.cf | 2 +- roles/MX/files/etc/postfix/virtual/domains.cf | 2 -- roles/MX/files/etc/postfix/virtual/list.cf | 2 +- roles/MX/files/etc/postfix/virtual/mailbox.cf | 2 +- roles/common/templates/etc/postfix/master.cf.j2 | 14 ++++++-------- 8 files changed, 12 insertions(+), 16 deletions(-) (limited to 'roles') diff --git a/roles/MX/files/etc/postfix/reject-unknown-client-hostname.cf b/roles/MX/files/etc/postfix/reject-unknown-client-hostname.cf index 6969f75..1f61f4b 100644 --- a/roles/MX/files/etc/postfix/reject-unknown-client-hostname.cf +++ b/roles/MX/files/etc/postfix/reject-unknown-client-hostname.cf @@ -1,4 +1,4 @@ -server_host = ldapi://%2Fvar%2Fspool%2Fpostfix-mx%2Fprivate%2Fldapi/ +server_host = ldapi://%2Fprivate%2Fldapi/ version = 3 search_base = fvd=%d,ou=virtual,dc=fripost,dc=org domain = static:all diff --git a/roles/MX/files/etc/postfix/virtual/alias.cf b/roles/MX/files/etc/postfix/virtual/alias.cf index 1c104a9..2e846ca 100644 --- a/roles/MX/files/etc/postfix/virtual/alias.cf +++ b/roles/MX/files/etc/postfix/virtual/alias.cf @@ -1,4 +1,4 @@ -server_host = ldapi://%2Fvar%2Fspool%2Fpostfix-mx%2Fprivate%2Fldapi/ +server_host = ldapi://%2Fprivate%2Fldapi/ version = 3 search_base = fvd=%d,ou=virtual,dc=fripost,dc=org domain = static:all diff --git a/roles/MX/files/etc/postfix/virtual/alias_domains.cf b/roles/MX/files/etc/postfix/virtual/alias_domains.cf index 907166f..1108ea1 100644 --- a/roles/MX/files/etc/postfix/virtual/alias_domains.cf +++ b/roles/MX/files/etc/postfix/virtual/alias_domains.cf @@ -1,4 +1,4 @@ -server_host = ldapi://%2Fvar%2Fspool%2Fpostfix-mx%2Fprivate%2Fldapi/ +server_host = ldapi://%2Fprivate%2Fldapi/ version = 3 search_base = ou=virtual,dc=fripost,dc=org domain = static:all diff --git a/roles/MX/files/etc/postfix/virtual/catchall.cf b/roles/MX/files/etc/postfix/virtual/catchall.cf index e0e6350..a67d39c 100644 --- a/roles/MX/files/etc/postfix/virtual/catchall.cf +++ b/roles/MX/files/etc/postfix/virtual/catchall.cf @@ -1,4 +1,4 @@ -server_host = ldapi://%2Fvar%2Fspool%2Fpostfix-mx%2Fprivate%2Fldapi/ +server_host = ldapi://%2Fprivate%2Fldapi/ version = 3 search_base = ou=virtual,dc=fripost,dc=org domain = static:all diff --git a/roles/MX/files/etc/postfix/virtual/domains.cf b/roles/MX/files/etc/postfix/virtual/domains.cf index f5a7f25..88e17e2 100644 --- a/roles/MX/files/etc/postfix/virtual/domains.cf +++ b/roles/MX/files/etc/postfix/virtual/domains.cf @@ -1,5 +1,3 @@ -# XXX: How come we use a socked relative to the chroot here?
