Question

I have a php app which is deployed on Heroku. How do I get the PEAR mail package to work for my app? I see two main options:
1) install pear mail package on heroku
2) Bundle the package into my app before deployment

Unfortunately I’m more of a rails guy so not sure how to do either of these (or which one is right).

Thanks,
Antony

OK, I finally figured this out myself. Here’s what I did:

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.git

The key changes are the addition of the lines:

php/bin/pear install mail
php/bin/pear install Net_SMTP

Into 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
 );
