我想整 OpenBSD 已经蓄谋已久了: 在 Windows 和 Fedora(160G) 之间我空出了 100G,

** ksh
|
||||
只写 .profile 不够, 还得在 .xsession 里加 ~ENV=$HOME/.profile~,
|

这样 ksh 才能每次加载配置, 否则只有 login shell 能
|

** v2ray

** email
|

既然在一个传统 UNIX 上, 那就试试终端邮件客户端, 然后试试订阅 OpenBSD 邮件列表.
|
||||
然后就按照这篇文章[fn:7]里面配置 smtpd 和 mail,
|
||||
试了好久都不行, 好乱.
|
||||
那就试试别的? 我切回 Fedora 看了几个 YouTube 视频, 里面都用 ssmtp, 那就试试?
|
||||
也试了好久, 发现是网易邮箱不支持 starttls! 估计 smtpd 也是这个原因.
|
||||
然后切回 OpenBSD, 没有 ssmtp? 那试试传说中的 mutt 吧!
|
||||
经过上面两个摧残之后这个配置感觉容易多了(注意启用 sasl), 很容易就发出了第一封邮件, 然后是怎么收邮件.
|
||||
smtp 收不了邮件, 得用 pop 或 imap
