• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

trouble with php and email

Redouble

New Pleskian
I'm having a few issues with my dedicated Windows server that has a Plesk panel

1.) I can't send e-mail via PHP's*mail()*function, it always returns the following error:SMTP server response: 550 Requested action not taken: mailbox unavailable or not localWhich setting should I alter in order to enable sending mail?

2.) The*exec()*and*passthru()*PHP functions don't work; their outputs are blank even when I try to run simple commands such as*dir. Is there an option that I can toggle in the control panel to enable this functionality?
