how to make a simple php app send emails from heroku cedar stack?
Here's what I did to solve this same problem:
1.You need to use a custom buildpack which installs the pear packages mail and Net_SMTP. You can use the one I created by running the following command:
heroku config:add BUILDPACK_URL=https://github.com/antonyevans/heroku-buildpack-php.gitThe key changes are the addition of the lines:
php/bin/pear install Mailphp/bin/pear install Net_SMTPInto bin/compile.
2.Then you need to tell your application to load the mail package:
require_once 'Mail.php';3.Finally heroku blocks the mail port so you need to configure to use an external mail server. For example if you have added the SendGrid addon ('heroku addons:add sendgrid:starter') then you could use the following:
$wgSMTP = array( 'host' => 'tls://smtp.sendgrid.net', 'IDHost' => 'heroku.com', 'port' => 587, 'username' => getenv("SENDGRID_USERNAME"), 'password' => getenv("SENDGRID_PASSWORD"), 'auth' => true );
