问题 I am almost done with a tool to detect if email is valid or not. I am stuck at small point where I have to detect If mail server or domain has catch-all policy enable. Catch all: mail server will accept all email even if email address do not exits. Thank you. 回答1: There is no 100% reliable way to detect a catch-all of a mail server you don't control yourself.

zabbix监控之邮件报警sendmail

阅读更多关于 zabbix监控之邮件报警sendmail

zabbix监控之邮件报警在zabbix的使用中，最重要的一点就是完善的报警机制，作为监控平台，需要时刻关注机器和服务的运行状态，更重要的是发现故障之后需要及时的报警给相关人员，早点发现问题，将隐患消除在未然阶段。这样才能保证服务的稳定运行。报警的方式是多种多样的，微信、短信和邮件报警是我们比较常见的方式。而且报警的频率和策略直接影响着运维人员的重视程度和检错效率。如果整个报警列表中都是一些无关痛痒的提示、轻度警告。而他们的发送频率又特别的高，则非常容易错过真正关键的报警。报警涉及的触发器（trigger）一般包括以下几个方面：（1）服务器的基本状态：磁盘容量、内存大小、cpu的负载；（2）基础服务状态：web服务器（nginx、apache）的状态，数据库的状态（mysql、oracle、nosql等）；（3）应用服务器状态：应用服务器的可用性以及负载状态；以本人之前所在的游戏公司为例，日常的监控报警中主要集中在服务器的基本状态的报警：（1）比如随着服务器的运行，会产生大量的日志文件，因为来不及转移导致服务器的磁盘可用空间不足；（2）开启的应用过多导致cpu和内存的不足；第一种磁盘不足的情况，可以采用crontab定期清理日志的方式解决，注意为了防止日志内容的丢失，需要把日志及时的备份到远程的日志服务器中进行存放；

Writing a simple email server

问题 What would be a good starting point for me to learn about creating an email server? Basically, what I want to do is have a server (such as foo.com) recieving mail for me so if I send an email to (blah@foo.com) it will dump the contents of the email into /mail/blah/subject and then send it off to my REAL email account. I'm looking to do this as a programming exercise, so links to RFCs, etc. would be nice. Reinventing the wheel is a good way to learn about wheels. EDIT: Feel free to retag this
