概要


在ARPANET時期，艾瑞克·歐曼開發了delivermail軟體，隨附在BSD 4.0與4.1版。隨著TCP/IP協定問世並且為BSD 4.1c所納入支援，他以delivermail為基礎另外分支出Sendmail。


2001年時的調查，網際網路上的郵件伺服器有42%使用Sendmail[1]。但之後由於多次被發現重大的安全性漏洞，且其設定檔過於複雜造成較高的學習門檻[2]等因素，導致市佔率下滑。2012年元月由E-Soft公司做的調查，僅12.43%的郵件伺服器使用Sendmail[3]。其市佔率被Exim、Postfix、Microsoft Exchange Server等新興的郵件傳送代理軟體所瓜分。



後續發展


下一世代的Sendmail最初命名為「Sendmail X」（先前名為「Sendmail 9」），但程式碼並不是分支自現有的Sendmail 8.x版，第一版已於2005年10月30日發行。授權許可與Sendmail 8.x相同。。


Sendmail X的最後一版smX-1.0.PreAlpha7.0，於2006年5月20日發行。之後由新的計劃「MeTA1」所取代。

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
