我需要帮助将服务器中的后缀配置为多个虚拟域和子域的收件人和发件人。我希望从此服务器的任何本地收件人发送的每封电子邮件都能通过其自己的虚拟域到达目的地，无论它是否是本地投递。
我已将 main.cf 设置为在其自己的虚拟主目录中接收每封电子邮件（“virtual_user@virtual_domain”）；到目前为止，一切正常。但是，当我尝试从此服务器的任何收件人向本地或外部收件人发送电子邮件时，电子邮件将使用此服务器的主机名作为其域（“virtual_user@hostname”）。
服务器：Linux姓名3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux
Postfix 2.11.3-1
名称.域名是服务器的 FQDN。
这是我的 main.cf

答案1
在main.cf：
canonical_maps = hash:/etc/postfix/canonical
然后在/etc/postfix/canonical：
user1 user1@domain
user2 [email protected]
