Email catch-all

All your projects can send emails to whatever recipient. You do not have to worry that they will actually being sent. Each PHP container runs a local postfix mailserver that intercepts all outgoing mails and puts them into a local mailbox by the user devilbox.

In order to view sent emails open up the devilbox intranet http://localhost/mail.php. There you can also test email sending and verify that they really stay locally.

In the above image from the intranet you can see that all emails sent to whatever recipient have been caught by the Devilbox and are available to be read.
