我的虚拟服务器上有一个多域设置：
master.cf：
127.0.0.1:smtp inet n - n - - smtpd
-o syslog_name=postfix-localhost
-o smtp_helo_name=localhost
-o smtp_bind_address=127.0.0.1
-o myhostname=localhost
-o smtpd_client_connection_count_limit=100
-o smtpd_tls_key_file=/etc/letsencrypt/live/the-grue.de-0001/privkey.pem
-o smtpd_tls_cert_file=/etc/letsencrypt/live/the-grue.de-0001/fullchain.pem
95.129.55.226:smtp inet n - n - - smtpd
-o syslog_name=postfix-mail.the-grue.de
-o smtp_helo_name=mail.the-grue.de
-o smtp_bind_address=95.129.55.226
-o myhostname=mail.the-grue.de
-o smtpd_client_connection_count_limit=100
-o smtpd_tls_key_file=/etc/letsencrypt/live/the-grue.de-0001/privkey.pem
-o smtpd_tls_cert_file=/etc/letsencrypt/live/the-grue.de-0001/fullchain.pem
95.129.55.232:smtp inet n - n - - smtpd
-o syslog_name=postfix-mail.maennerchor-kirchseeon.de
-o smtp_helo_name=mail.maennerchor-kirchseeon.de
-o smtp_bind_address=95.129.55.232
-o myhostname=mail.maennerchor-kirchseeon.de

-o smtpd_tls_cert_file=/etc/letsencrypt/live/maennerchor-kirchseeon.de-0001/fullchain.pem
95.129.55.223:smtp inet n - n - - smtpd
-o syslog_name=postfix-mail.goldschmiede-grunwald.de
-o smtp_helo_name=mail.goldschmiede-grunwald.de
-o smtp_bind_address=95.129.55.223

-o smtpd_tls_cert_file=/etc/letsencrypt/live/goldschmiede-grunwald.de/fullchain.pem
the-grue-out unix - - n - - smtp
-o smtp_bind_address=95.129.55.226
-o smtp_helo_name=mail.the-grue.de
-o syslog_name=postfix-mail.the-grue.de
maennerchor-kirchseeon-out unix - - n - - smtp
-o smtp_bind_address=95.129.55.232
-o smtp_helo_name=mail.maennerchor-kirchseeon.de
-o syslog_name=postfix-mail.maennerchor-kirchseeon.de
goldschmiede-grunwald-out unix - - n - - smtp
-o smtp_bind_address=95.129.55.223
-o smtp_helo_name=mail.goldschmiede-grunwald.de
-o syslog_name=postfix-mail.goldschmiede-grunwald.de
总体来说，这种方法效果很好。但我定义了一些虚拟别名：
虚拟别名：
[email protected] [email protected], [email protected]
如果有人向 发送电子邮件[email protected]，有时它来自 95.129.55.232，但有时它来自 95.129.55.226。在后一种情况下，它当然被视为垃圾邮件。
编辑：我在 main.cf 中有这个：
sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport
这就是的内容/etc/postfix/sender_transport：
# Use source IP - 95.129.55.226
@the-grue.de the-grue-out:
# Use source IP - 95.129.55.232
@maennerchor-kirchseeon.de maennerchor-kirchseeon-out:
# Use source IP - 95.129.55.223
@goldschmiede-grunwald.de goldschmiede-grunwald-out:
我postmap /etc/postfix/sender_transport编辑完之后就跑了。
我配置错了什么？我发现了很多类似的问题，考虑域名或单域设置，但对于我的用例，我没有发现任何东西。
