php email mode no longer available

I'm running nextcloud on a hosted server.
After the upgrade from 13 to 14, emails were no longer working.
It seems php support has been removed. In my case only SMTP support is available as the hosted environment does not have a /usr/sbin/sendmail binary.

Configuring SMTP mode is very inconvenient, as I now need to create a special email account.

Please consider adding back support for php mode.
