Email

WordPress environments on the VIP Platform are configured to route transactional email (e.g., password resets, user registration notifications) through WPVIP’s mail servers.

By default, transactional emails are sent from the email address donotreply@wpvip.com. It is possible to override the default sender’s email address and send emails from a custom domain instead.

The WordPress wp_mail() function can be used in custom code to send small amounts of emails to admins or other specific email addresses. But to prevent issues with spam, abuse, or other unwanted communications, any custom code using  wp_mail() should not generate (or allow users to generate) email messages to site users or user-supplied email addresses.

Limitations

• VIP’s infrastructure for message delivery is not intended for the distribution of HTML emails, mailing list functionality, invitations to view or share content, notifications of site activity, or other messages generated in bulk. A third-party SMTP (Simple Mail Transfer Protocol) service or ESP (Email Service Provider) should be used for these purposes, and can be integrated with a plugin or custom code.
• The size of a message sent through WPVIP’s mail servers—after encoding—cannot exceed 100 MB.
• The email address of the sender cannot be modified for emails that are sent by the Jetpack Subscription feature.
• Convenience domains cannot be used for sending emails.

Enable uploaded files to be sent as attachments

Media files that are uploaded to a WordPress site are not stored on the web container’s filesystem. Instead, uploaded files are stored in the VIP File System which is a separate object store. To send a file stored in the VIP File System as an attachment in an email, the VIP constant USE_VIP_PHPMAILER must be defined as true invip-config.php.

define( 'USE_VIP_PHPMAILER', true );

Email logs

Customers can optionally add an email log plugin to have more visibility into outgoing emails. Email log plugins often provide the ability to verify that an email has been sent, where it has been set, when it was sent, and its content. When considering plugin candidates for an email log plugin, follow the guidelines for evaluating a third-party plugin before adding or enabling the plugin in a production environment.

Disable email

Use the vip_block_wp_mail filter to disable all outgoing emails from a WordPress site, including transactional emails (e.g., password resets, user registration notifications).

To disable emails, add the following code to a file in /client-mu-plugins:

add_filter( 'vip_block_wp_mail','__return_true' );
