我想组织sendmail队列以减少活动队列并使邮件更快。
我想设置sendmail，以便在第一时间只连接快速服务器（conn.time小于5秒）。
如果conn.time＆gt; 5s，然后sendmail会将此消息从活动队列放到文件夹'/var/spool/mqueue/slow'
每小时sendmail都会尝试从文件夹'slow'重新发送邮件。
如果来自文件夹'slow'的消息存在连接超时，sendmail会将此消息发送到文件夹'/var/spool/mqueue/veryslow'
每8小时sendmail将尝试重新发送文件夹'veryslow'中的邮件。
例如，我有几封电子邮件。我是通过sendmail发送的。
mail@fast-server (connection time less than 5s)
mail@slow-server (connection time 20s)
mail@dead-server (connection time infinitely)
结果将是
mail@fast-server - sent
mail@slow-server - will be in folder 'slow' because of connection timeout
mail@dead-server - will be in folder 'slow' because of connection timeout
结果将在1小时后
mail@slow-server - sent (from 'slow' folder)
mail@dead-server - will be in folder 'veryslow' because of connection timeout
8小时后的结果
mail@dead-server - sendmail try to resend message from folder 'veryslow'.
If connection timeout, sendmail must delete this message.
我需要写入sendmail.mc来配置它吗？
这是我的配置，但我无法完成。
