3. postfixのinstall
yum でpostfixのinstall。% sudo yum install postfix
4. postfixのvirtual用unix user作成
virtual mail 受取用のunix user「vhost」を作成。 ここでは、user idを「5000」とする。% sudo useradd -u 5000 vhosts
5. postfixのsetup
ファイルのそれぞれ修正する。例は、「sample.com」。/etc/postfix/main.cf
myhostname = mail.sample.com myhostname = mail.sample.com myorigin = $mydomain inet_interfaces = all #mydestination = $myhostname, localhost.$mydomain, localhost home_mailbox = Maildir/ # add virtual_mailbox_domains = sample.com virtual_mailbox_base = /var/vhosts virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid = 100 virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 # smtp auth on ssl disable_vrfy_command = yes smtpd_use_tls = yes smtpd_tls_auth_only = yes tls_random_source = dev:/dev/urandom smtpd_tls_cert_file = /etc/pki/tls/certs/postfix.crt smtpd_tls_key_file = /etc/pki/tls/certs/postfix_nopass.key smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination virtual_alias_maps = hash:/etc/postfix/valias_map
/etc/postfix/master.cf
smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o milter_macro_daemon_name=ORIGINATING
/etc/postfix/virtual
sample.com anything
6. postfix用認証情報の作成
% cd /etc/pki/tls/certs % sudo make postfix.key % sudo make postfix.csr % sudo make postfix.crt
さらに、posfix.keyのpassphraseなし版を作成。
% sudo openssl rsa -in postfix.key -out postfix_nopass.key
