php - PHP Sendmail 参数 Linux

Question

/usr/sbin/sendmail -t -i

我知道 -t 参数告诉 Apache 可以通过 php 发送电子邮件。

-i 参数有什么作用？还有更多值得了解的论点吗？

我知道的另一个是 -f myemail@example.com，它是来自覆盖的发送邮件。

Answer 1

   -i        This  option,  which  has  the  same  effect  as  -oi, specifies that a dot on a line by itself should not terminate an incoming,
             non-SMTP message. I can find no documentation for this option in Solaris 2.4 Sendmail, but the mailx command in Solaris 2.4  uses
             it. See also -ti.

*至于你的问题：*

 -i          Ignore dots alone on lines by themselves in incoming mes-
                 sages.  This should be set if you are reading data from a
                 file.
