回复: 关于 dovecot 的expire plugins

过滤部分还要测试

能否贴一段 deliver 过程的debug日志，看看与我的有什么不同

谢谢


什么情况下的 debug？
在 Dovecot-1.1.5 里大幅度改进了对 error log 的提示信息，所以 1.1.5 里对发生的问题应该更容易定位才对。

OK.

在 dovecot.conf 中启用 'mail_debug = yes' 参数，并设置 quota_warning 如下（为了方便测试，我设置了多个 quota_warning）：

plugin {
    quota_warning = storage=95%% /usr/bin/quota-warning.sh 95
    quota_warning2 = storage=80%% /usr/bin/quota-warning.sh 80
    quota_warning3 = storage=60%% /usr/bin/quota-warning.sh 60
    quota_warning4 = storage=40%% /usr/bin/quota-warning.sh 40
}

重启启动 dovecot 服务，立刻可以在屏幕上看到以下内容：

IQuota warning: bytes=9961472 (95%) messages=0 (0%) command=/usr/bin/quota-warning.sh 95
IQuota warning: bytes=8388608 (80%) messages=0 (0%) command=/usr/bin/quota-warning.sh 80
IQuota warning: bytes=6291456 (60%) messages=0 (0%) command=/usr/bin/quota-warning.sh 60
IQuota warning: bytes=4194304 (40%) messages=0 (0%) command=/usr/bin/quota-warning.sh 40

这时候往用户的邮箱里发邮件，达到任意一个之后，sieve 的投递日志里会出现类似的记录：

已经触发，并且发送了邮件出去了。

在上面贴的 sieve.log 的日志里，倒数第二行就是：

deliver(www@a.cn): Oct 28 19:30:49 Info: msgid=: saved mail to INBOX

msgid 为空，是因为它不经过 Postfix，直接有 deliver 程序生成。

最直接的证明就是用户已经收到 quota_warning 发送的邮件通知了。
