如何根據 From：Debian 上 exim4 中的地址選擇智能主機

我想路由帶有 From: through 的電子郵件和帶有 From: .*@host1.comthrough的smtp.server1.com電子郵件。.*@host2.com``smtp.server2.com

目前，我已將 smarthost 配置為dpkg-reconfigure exim4-config包含update-exim4.conf.conf該行 dc_smarthost='smtp.server1.com::587'。也就是說，一切都通過smtp.server1.com.

我嘗試在配置文件中的定義之前添加另一個路由器smarthost:，設置senders = .*@host2.com

smarthost_server2:
 debug_print = "R: smarthost_server2 for $local_part@$domain"
 driver = manualroute
 domains = ! +local_domains
 transport = remote_smtp_smarthost
 senders = .*@host2.com
 route_list = * smtp.server2.com byname
 host_find_failed = ignore
 same_domain_copy_routing = yes
no_more

但 exim 仍然通過smtp.server1.com. 我senders是否正確使用條件？

AFAIU，對於有電子郵件的人來說，這應該是一個相當常見的設置。@google.com 和 . @gmail.com 不想在他們的@gmail.com 電子郵件標題中透露他們也是Google員工的事實，所以路由應該不同。

好，我知道了。senders是 /etc/mailname 提供的，而不是 From 的域部分：

以下作品：

begin routers

smarthost1:
 driver = manualroute
 domains = ! +local_domains
 condition = ${if match_domain{${domain:$h_From:}}{domain.com}{yes}{no}}
 transport = remote_domain_com_smtp
 route_data = domain.com::587
 ignore_target_hosts = <; 0.0.0.0 ; 127.0.0.0/8 ; ::1

smarthost2:
 driver = manualroute
 domains = ! +local_domains
 condition = ${if match_domain{${domain:$h_From:}}{domain.org}{yes}{no}}
 transport = remote_domain_org_smtp
 route_data = domain.org::587
 ignore_target_hosts = <; 0.0.0.0 ; 127.0.0.0/8 ; ::1


begin transports

remote_domain_com_smtp:
 driver = smtp
 message_size_limit = ${if > {$max_received_linelength}{998} {1}{0}}
 hosts_require_auth = domain.com
 headers_remove = received
 return_path = ${address:$h_from:}


remote_domain_org_smtp:
 driver = smtp
 message_size_limit = ${if > {$max_received_linelength}{998} {1}{0}}
 hosts_require_auth = domain.org
 return_path = ${address:$h_from:}

wheredomain.com和domain.org分別是我要選擇的域。
