Using Sendmail in PHP

All PHP coders are aware of the mail() function in PHP, which can be used to send mails. On Linux systems we ussually have Sendmail program installed, if someone is facing a problem sending mails with mail() function, they can alternatively use Sendmail to send mails.
For sending mails using Sendmail we need to open a pipe to the sendmail program, which can be accomplished using the popen() function in php.

Example:

PHP:

    $fd = popen("/usr/sbin/sendmail -t","w") or die("Couldn't Open Sendmail");
    fputs($fd, "To: recipient@hisdomain.com \n");
    fputs($fd, "From: \"Your Name\" <youremail@yourdomain.com> \n");
    fputs($fd, "Subject: Test message from my web site \n");
    fputs($fd, "X-Mailer: PHP3 \n\n");
    fputs($fd, "Testing. \n");
    pclose($fd);

 

do you know this is cannot send emails to hotmail or yahoo accounts.
How to make it success

 

May be your IP is in the not-trusted list. Check your IP for a block here http://www.spamhaus.org/sbl/index.lasso

 

hotmail, aol and some others have huge problems in receiving the emails due to their spam filters. I would recommend sending emails via SMTP

 

Or...a fresh IP of the server )
