xinetd 代理 SMTP 和 IMAP

通过 xinetd 代理 SMTP 和 IMAP 实现 gmail 翻墙。

1. 配置服务端

   service imap
   {
   		type = UNLISTED
   		port = 993
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = imap.gmail.com 993
   		per_source = UNLIMITED
   		cps = 100 2
   }
   service smtp-465
   {
   		type = UNLISTED
   		port = 465
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = smtp.gmail.com 465
   		per_source = UNLIMITED
   		cps = 100 2
   }
   service smtp-587
   {
   		type = UNLISTED
   		port = 587
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = smtp.gmail.com 587
   		per_source = UNLIMITED
   		cps = 100 2
   }
   

2. 本机修改 hosts

   echo '45.115.36.35 smtp.gmail.com' | sudo tee -a /etc/hosts
   echo '45.115.36.35 imap.gmail.com' | sudo tee -a /etc/hosts
   

通过滴滴云穿透和加速 gmail 代理

1. 通过在滴滴云上配置

   service imap
   {
   		type = UNLISTED
   		port = 993
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = 45.115.36.35 993
   		per_source = UNLIMITED
   		cps = 100 2
   }
   service smtp-465
   {
   		type = UNLISTED
   		port = 465
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = 45.115.36.35 465
   		per_source = UNLIMITED
   		cps = 100 2
   }
   service smtp-587
   {
   		type = UNLISTED
   		port = 587
   		bind = 0.0.0.0
   		socket_type = stream
   		wait = no
   		user = nobody
   		redirect = 45.115.36.35 587
   		per_source = UNLIMITED
   		cps = 100 2
   }
   

2. 调整本地 hosts

   echo '117.51.146.119 smtp.gmail.com' | sudo tee -a /etc/hosts
   echo '117.51.146.119 imap.gmail.com' | sudo tee -a /etc/hosts
