I'm using OpenShift and I have problem sending email.
It works fine when logged in via ssh, for eg:
echo “Test from Postfix” | mail -s “Test1″ me@yahoo.com
However if I want to send an email from php code like this:
if (mail ('me@yahoo.com', "Test Postfix", "Test mail from postfix", "From: somebody@example.com"))
echo "mail sent succesfully";
else
echo "couldn't send mail";
It writes "mail sent succesfully", but no email arrives :( Tried without header too, but it's the same.
Checked the settings for smtp, sendmail_path, sendmail_from and smtp_port, both with php -i and phpinfo(). They are the same:
error.log contains no error. I can't find the email.logs.
Can you suggest some solution?
As far as I know, you need a real sender account in order to make it. That's probably why the other answers suggest plugins/libraries. So you need to provide not only a valid SMTP server, but also an account and pass. Agreed however, that it lacks information about the mail not being sent.
Could be getting caught in the outgoing spam filter, depending on the content etc.
The plugin WP Mail SMTP was a solution for me. Read the howtos here: http://www.wpbeginner.com/plugins/how-to-send-email-in-wordpress-using-the-gmail-smtp-server/
I would recommmed checking out the following StackOverflow question: Can't send email through openshift
It sorted everything out for me, and you can define all the variables using the PHPMailer. I spent a few hours trying to do what you were trying to do with PHP within Openshift, but found this plugin solved it almost immediately.
