Answer 1

IS that possible to check with phpinfo() output? 是否可以通过phpinfo（）输出进行检查？

Not always, and not reliably. 并非总是如此，也不可靠。 But why not simply try out? 但是为什么不简单地尝试一下呢？

mail("youraddress@domain.com", "Test subject", "Test body");

Answer 2

您可以检查phpinfo()但我建议尝试

mail("me@me.com", 'Subject', 'Test Body', "From: from@me.com");

Answer 3

You can fsock open on the mail server's port also. 您也可以在邮件服务器的端口上打开fsock。 This is playing on nightmare mode however. 但是，这是在噩梦模式下播放的。
