Drupal 7不发送电子邮件

Question

I've a website created with drupal 7 with a customized theme, all seems to be fine except the contact form is not working.

I have tested the server installation using a very basic PHP script to send emails, and the server seems to be well configured, but still Drupal does not send the emails.

As I'm less than a newbie in drupal, can any one tell me what I need to check to know where the problem is coming from, that I can hopefully fix it ?

Further informations:

• I have confirmed that the contact module is activated
• I check the permissions, and every body is allowed to send emails
• I don't get any error after filling the contact form and sending it.

UPDATE

This is the scritp I used to test if my server is configured to send emails:

<?php
    $to = "myemail@domaine.com";
    $subject = "Hi!";
    $body = "Hi,\n\nHow are you?";
    if (mail($to, $subject, $body)) {
            echo("<p>Message successfully sent!</p>");
    } else {
            echo("<p>Message delivery failed...</p>");
    }

Answer 1

As GeoPhonix suggested to me, I had a look on the log files on my server /var/log/mail.lo and I noticed that the email was sent but to a different email address which was set there by the website creator, and as I'm a less than newbie I could figure where the email address was set, following are the steps I solved my problem with:

---

1. using the command tail -f /var/log/mail.log I could watch the log changes
2. I sent an email using the drupal contant page
3. I noticed the log changed, and the email was successfully sent to a wrong email address.
4. I didn't know where to change the email so I search using phpmyadmin the whole database to fin the email in the webform table
5. I search every part in drupal administrative interface where the word webform was mentioned to find where to change the email config
6. after some time I find it in: content -> contact page -> webform -> emails and there was the email specified differently from the default contact email.

I just wanted to write what I did, may be someone will have the same issue or a similar one, that he can have a idea how to debug things
