Postfix 使用 virtual.db 文件而不是 mysql 表

  • June 20, 2019

我已經指定virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf了,但我仍然收到類似的錯誤

警告:hash:/etc/postfix/virtual 不可用。打開數據庫/etc/postfix/virtual.db:沒有這樣的文件或目錄

如果我創建 virtual 和 virtual.db 文件,一切正常,但我希望我的虛擬使用者帳戶儲存在 DB 中,而不是文件。

為什麼 postfix 使用 virtual.db 文件而不是 db 表?

postconf -n:

alias_maps = hash:/etc/aliases
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
dovecot_destination_recipient_limit = 1
inet_interfaces = all
inet_protocols = ipv4
milter_default_action = accept
milter_protocol = 2
mydestination = localhost
non_smtpd_milters = unix:/var/run/opendkim/opendkim.sock
smtp_tls_note_starttls_offer = yes
smtpd_milters = unix:/var/run/opendkim/opendkim.sock
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = example.tst
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous
smtpd_sasl_type = dovecot
smtpd_tls_auth_only = no
smtpd_tls_cert_file = /etc/dovecot/dovecot.pem
smtpd_tls_key_file = /etc/dovecot/private/dovecot.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_security_level = may
smtpd_tls_session_cache_timeout = 3600s
smtpd_use_tls = yes
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 = dovecot

實際上我在master.cf中有/etc/postfix/virtual:

submission inet n - - - - smtpd
 -o smtpd_tls_security_level=encrypt
 -o smtpd_sasl_auth_enable=yes
 -o smtpd_sasl_type=dovecot
 -o smtpd_sasl_path=private/auth
 -o smtpd_sasl_security_options=noanonymous
 -o smtpd_sasl_local_domain=$myhostname
 -o smtpd_client_restrictions=permit_sasl_authenticated,reject
 -o smtpd_sender_login_maps=hash:/etc/postfix/virtual
 -o smtpd_sender_restrictions=reject_sender_login_mismatch
 -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject

問題是-o smtpd_sender_login_maps=hash:/etc/postfix/virtualmaster.cf 中的行。我忘了看那裡,因為這個確切的配置在我的另一台伺服器上執行了幾個月。

我通過修改以下行解決了這個問題etc/postfix/main.cf

virtual_alias_maps = hash:/etc/postfix/virtual

virtual_alias_maps = hash:/etc/aliases

(或者作為替代方案,只需創建etc/postfix/virtual包含內容的文件):

your_linux_username:  your_email@gmail.com

然後重新啟動 postfix: sudo systemctl restart postfix然後發送郵件。
