<p>This plugin when activated automatically redirects all email sent through wp_mail/phpmailer to the user currently logged in or the site administrator.</p>
<p>The redirected email contains information about where the original email would have been sent to.</p>
<p>Use this plugin if you want to test email-sending features without actually sending emails our to anyone but yourself. I wrote this plugin to ease debugging with subscribe2.</p>
<p>Since Version 1.2 you can choose whether to redirect all email to the currently logged in user (default), the site administrator (only wpmu) or the blog administrator.</p>


Mail Debug

Redirects all email sent through wordpress to the user currently logged in or the site administrator.

<p><strong>WPO365 | MS GRAPH MAILER</strong> provides you with a modern, reliable and efficient way to send WordPress transactional emails from one of your Microsoft 365 / Exchange Online / Mail enabled accounts.</p>
<p>The plugin re-configures your WordPress website to send emails using the <strong>Microsoft Graph API</strong> instead of – for example – SMTP. Sending WordPress emails using the <strong>Microsoft Graph API</strong> has become the only available alternative after Microsoft has disabled basic authentication (username and password) over the SMTP protocol.</p>

<li>Or: Select either a Microsoft 365 account or a personal Microsoft account, like Hotmail.com or Outlook.com, to send WordPress emails.</li>
<li>Or: Configure <a href="https://learn.microsoft.com/en-us/Exchange/permissions-exo/application-rbac" rel="nofollow ugc">RBAC for Exchange Online</a> and authorize as an application but with a limited scope e.g. one specific mailbox.</li>
