Sendmail 问题：已成功发送但从未到达

Question

I'm trying to send mail via the PHP mail() function which as far as I have understood uses sendmail to deliver the goods. Now my problem is that mail() returns true but there is not even a trace of the mail in my mailbox (yea i checked spam too).

So i tried to send some mail manually from the terminal but the problem persists. sendmail does not give me an error, except from a unable to determine domain error which i fixed by adding the domain for my dev-machine to /etc/hosts and related it to 127.0.0.1.

andreas@Andreas-PC-Ubuntu:~$ sendmail xxxxxxx@xxxxxxx.com
Test
.
andreas@Andreas-PC-Ubuntu:~$

As well as giving no error, sendmail logs that the mail was sent successfully in /var/log/mail.log:

So yea, any suggestions?

Answer 1

Are you sure the recipient SMTP server isn't dropping (or at least greylisting) your mail? It's very common for mail servers to treat messages not coming from a recognized MX server as being spammy.

Is sendmail configured to use an SMTP relay/smarthost? If not, what happens if you configure it to use your ISP's, employer's, or other hosting provider's server?

Answer 2

have you set up the configuration in your php.ini file?

When i setup php on my own server (I was running IIS on server 2003, with Exchange for emails), I had to edit the php.ini file to configure the Mail function.

Just had to uncomment andspecify my mail server for the SMTP part.

Edit

[mail function]; For Win32 only. ; http://php.net/smtp SMTP = #mymailserver#; http://php.net/smtp-port smtp_port = 25

You will probably have to do the same, or similar, depending on your web server environment
