后缀 - status=bounced（未知用户“myuser”）

Question

我正在配置 Postfix，当通过 telnet 和 SMTP 进行验证时，我收到状态退回错误，未知用户：

错误日志：

postfix/local[18718]：4590D7DC0A51：to=，relay=local，delay=9.8，delays=9.8/0.01/0/0.04，dsn=5.1.1，status=bounced（未知用户：“myuser”）

“myuser”已经存在，但具有完整的域名：myuser@mydomain.com。

用户验证：

 postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf

输出是：“1” - 所以我想没问题。

我的后缀配置：

root# postconf -n:
append_at_myorigin = yes
biff = no
config_directory = /etc/postfix
default_destination_concurrency_limit = 1
delay_warning_time = 8h
disable_vrfy_command = yes
dovecot_destination_concurrency_limit = 1
dovecot_destination_recipient_limit = 1
enable_original_recipient = yes
local_destination_concurrency_limit = 1
maximal_queue_lifetime = 6d
mydestination = mydomain.com
smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated
smtpd_delay_reject = no
smtpd_hard_error_limit = 10
smtpd_helo_required = yes
smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname
smtpd_recipient_restrictions = permit_mynetworks, reject_unknown_sender_domain,             reject_unknown_recipient_domain, reject_unlisted_recipient, reject_unauth_destination, reject_unauth_pipelining
smtpd_sender_restrictions = permit_mynetworks, reject_unknown_sender_domain
smtpd_soft_error_limit = 5
strict_rfc821_envelopes = yes
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf,mysql:/etc/postfix/mysql-email2email.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

感谢您的帮助。

Answer 1

您已添加mydestination = mydomain.com，因此mydomain.com 的有效用户将在local_recipient_maps 中搜索。从日志中可以清楚地看出，选择local 投递代理来投递邮件，因为本地域类匹配。更多帮助请见postfix address classes

如下修改你的 main.cf

#/etc/postfix/main.cf
mydestination = 
# set to localhost localhost.$mydomain or remove mydomain.com for now
# Ensure that postmap -q mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf is returning mydomain.com and 
# postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf succeeds

Answer 2

对于其他人，当我设置 mydestination=mydomain.com 时。 后缀显示警告不在 mydestination 和 virtual_mailbox_domains 中列出域 mydomain.com。所以我将它设置为relayhost = mydomain.com

我的 postfix 版本：3.1.0 (postconf -d | grep mail_version)

Answer 3

打开/etc/postfix/main.cf，查找mydestination字段并将其值更改为以下

mydestination = localhost, localhost.localdomain

之后别忘了运行sudo postfix reload

Answer 4

在 /var/postfix/main.cf 中使用以下设置

myorigin = localhost
myhostname = <your_host_name>
mydestination = localhost.$mydomain, localhost, localhost.localdomain

接着是：

sudo postmap /etc/postfix/virtual
sudo service postfix restart
