-I like to use a local smtp daemon for sending email from my laptop, because that way i can send emails even while disconnected and, even when the network is up, because i don't have to wait for the network protocol to be completed with a remote smarthost. Oh, and i also need local mail delivery.
+我喜欢使用本地 smtp 守护进程从我的笔记本电脑发送电子邮件，因为这样我即使在断开连接的情况下也可以发送电子邮件，而且，即使是在网络正常的情况下，因为我不需要等待网络协议在远程 smarthost 上完成。哦，我还需要本地邮件发送。
 
-For many years i've used postfix to those ends; it has an acceptably simply-ish configuration; but recently i've become fond of VPNs ([mullvad][1], if you want to know), and was annoyed by its getting confused when `/etc/resolv.conf` changes (for instance, because you get the VPN up after postfix's service has started). I've found a pleasantly simple alternative: [OpenSMTPD][2].

-Say i want to use the SMTP server fencepost.gnu.org when sending an email as [jao@gnu.org][3] and smtp.jao.io when writing with [mail@jao.io][4] or [news@xmobar.org][5] in my `From` header. OpenSMTPD let's you do that with a very simple configuration file in `/etc/smtpd.conf`[1][6]:
