我以为我在 Amazon Ubuntu 服务器上设置了所有 postfix 配置，但我想不是。我正在尝试为 3 个虚拟托管的 Apache 网站设置管理员电子邮件帐户。这是我的后缀 main.cf 文件：
myhostname = ip-XX-XXX-XX-XXX.us-west-2.compute.internal
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = ip-XX-XXX-XX-XXX.us-west-2.compute.internal, localhost.us-west-2.compute.internal, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
virtual_mailbox_domains = example1.com, example2.com, example3.com
virtual_mailbox_base = /var/mail/vhosts
virtual_mailbox_maps = hash:/etc/postfix/vmailbox
virtual_minimum_uid = 100
virtual_uid_maps = static:115
virtual_gid_maps = static:115
virtual_alias_maps = hash:/etc/postfix/virtual
这是我的 vmailbox 文件：
admin@example1.com example1.com/admin
admin@example2.com example2.com/admin
admin@example3.com example3.com/admin
@example1.com example1.com/catchall …
