Mailblock

Overview

Mailblock is a module for preventing drupal_mail() messages sent from development and staging sites from going to undesirable addresses. This is a good safety net, provided the site does actually send all its mail through drupal_mail -- the module will actually check that for you when you run the Drupal status report, and you should follow up any Mailblock warnings on that report as a matter of importance.

Features

• Send test emails.
• Whitelist.
• Permit delivery to the site domain.
• Scans for php mail() which can't be redirected.
• Safe files list for php mail() function.
• Raise a warning in the Drupal status report if the module is active on a live site (if configured correctly)

Similar modules

• Mail Redirect - redirects all mail to a different domain, not a fully different email address
• Reroute Email - Similar approach as this module and completely changes the outgoing email address, but without some of the extra features.
