Postfix其安装,但我如何测试

Question

我尝试了在线阅读的所有内容进行测试,但我无法收到电子邮件

telnet <IP> 25
EHLO
MAIL FROM: <from-email>
RCPT TO: <recipient-email>
DATA
Type message here.
. <Enter>
=>

我甚至试过这个,当我输入句号时我什么都没得到.....但是安装了postfix

Answer 1

检查postfix是否正在运行

sudo postfix status

如果它没有运行,请启动它.

sudo postfix start

然后telnet到localhost端口25以测试电子邮件ID

ehlo localhost
mail from: root@localhost
rcpt to: your_email_id
data
Subject: My first mail on Postfix

Hi,
Are you there?
regards,
Admin
.

别忘了.最后,表示行尾

Answer 2

(我刚刚开始工作,我的主要问题是我没有真正的互联网主机名,所以回答这个问题,以防有人帮忙)

您需要使用HELO指定主机名.即便如此,您应该收到错误,因此Postfix可能没有运行.

此外,=>不是命令.'.' 在没有任何文本的单行上是告诉Postfix条目完成的原因.以下是我使用的条目:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: somebody@blah.com
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

您应该收到如下回复:

250 2.0.0好的:排队为6E414C4643A

电子邮件可能会以垃圾文件夹结尾.如果它没有显示,那么您可能需要在没有真正的Internet主机名的主机上设置" Postfix ".以下是我在Ubuntu框中完成该步骤的细分:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
his@localdomain.local             hisaccount@hisisp.example
her@localdomain.local             heraccount@herisp.example
@localdomain.local                hisaccount+local@hisisp.example
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

快乐的小道
