APPideas Email Holinator

APPideas Email Holinator stops this site sending email, and records the messages it

held so you can see exactly what would have gone out.

The two switches that matter — Block emails and Log emails — are pinned to

the admin toolbar, one hover away from every screen in wp-admin. The toolbar icon

turns orange while mail is being logged and red while it is being held, so you can

tell at a glance what the site is doing with its email.

It adds one wp-admin screen and that toolbar item, and nothing else: no

public-facing frontend, no dashboard widgets, and no changes to the body of any

other admin page.

Holding

• Block emails holds everything that goes out through wp_mail(), before it reaches any mail transport — WordPress’s own, or an SMTP plugin’s.

• On WordPress’s own mail path a held message is answered as sent, so a held password reset or order confirmation does not turn into an error message on a site that was never meant to send it.

• Two constants for wp-config.php, AIEH_PERMAHOLE and AIEH_PERMALOG, force a switch on and lock it in the toolbar — for a development site seeded from production data, where forgetting once is once too many.

The log

• Log emails records every message sent through wp_mail() — sender, recipients, subject and body — held or not, and the Holinator screen lists them newest first with search, sort and a CSV download.

• Open a message to read it the way it would have arrived, with an HTML body rendered in a sandbox; resend it exactly as it was sent, or open a print-friendly view.

• A message the mail transport rejected is recorded as failed, with the transport’s own error, and the log keeps the newest 1,000 messages.

Tools

• A status card shows what the two switches are doing right now, and updates the moment a switch is flipped in the toolbar.

• Send a real test message through the current settings and read a step-by-step transcript of what happened to it.

External services

This plugin contacts no external service. Nothing is sent to APPideas or to any third

party, and there is no analytics, telemetry, licence check, or update service of any

kind.

APPideas Email Holinator PRO adds

• An allow list — the accounts and roles you name still get their mail while everything else stays held.

• A block list — mail goes out as usual, and only the accounts and roles you name are held.

• Forwarding — messages that match are redirected to one address you can read, and the log records where each one actually went.

• Rules are written against the WordPress users and roles you already manage, and act on messages with a single recipient.

PRO installs alongside this plugin rather than replacing it, and adds its controls to

the Tools tab of this plugin’s own screen. com/email-holinator/
