Postfix
postfix + virtual users (db) : 添加一個donotreply地址
我按照DigitalOcean的指南在 Centos 6.5 上設置了 postfix/dovecot/mysql 。
我的虛擬地址和別名工作得很好,現在我正在嘗試添加一個 donotreply 別名。
在我的虛擬使用者表中,我有
donotreply@mydomain.com
一個目標為devnull
.最後
/etc/aliases
我有devnull: /dev/null
我追
newaliases
了這個。檢查虛擬別名:
$ postmap -q donotreply@mydomain.com mysql:/etc/postfix/mysql-virtual-alias-maps.cf devnull
當我向此地址發送郵件時,我收到“使用者不存在”的退回郵件
devnull@mydomain.com
Mar 25 14:48:12 vps1 postfix/lmtp[7686]: 8543360392: to=<devnull@mydomain.com>, orig_to=<donotreply@mydomain.com>, relay=host.mydomain.com[private/dovecot-lmtp], delay=0.14, delays=0.07/0.01/0.01/0.05, dsn=5.1.1, status=bounced (host host.mydomain.com[private/dovecot-lmtp] said: 550 5.1.1 <devnull@mydomain.com> User doesn't exist: devnull@mydomain.com (in reply to RCPT TO command))
每次更改後都重新載入了 Postfix(和 dovecot),但仍然沒有運氣。
我的後綴配置:
$ postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 home_mailbox = Maildir/ html_directory = no inet_interfaces = all inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man milter_default_action = accept milter_protocol = 2 mydestination = localhost myhostname = host.mydomain.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix non_smtpd_milters = $smtpd_milters queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_milters = inet:127.0.0.1:8891 smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_tls_auth_only = yes smtpd_tls_cert_file = /path/to/ssl/cert smtpd_tls_key_file = /path/to/ssl/privatekey smtpd_use_tls = yes unknown_local_recipient_reject_code = 550 virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_transport = lmtp:unix:private/dovecot-lmtp
我還嘗試在 /etc/postfix/main.cf 中啟用本地收件人映射
local_recipient_maps = unix:passwd.byname $alias_maps
但這也沒有用。
我還創建了一個 devnull 本地使用者
$ useradd -M -d /dev/null -s /sbin/nologin devnull
但這也沒有改變。
如何獲得一個虛擬別名以重定向到 /dev/null?
您也可以使用DISCARD
丟棄可選文本…
聲明成功傳遞並靜默丟棄消息。如果指定,則記錄可選文本,否則記錄一般消息。
smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/virtual_access reject_unknown_recipient_domain permit_mynetworks permit_sasl_authenticated reject_unauth_destination # cat virtual_access no-reply@example.net DISCARD DEV-NULL # postmap virtual_access
發送簡單的消息
