Send mail via PHP not SMTP

[billynoah]

In past versions of Roundcube the smtp_server setting could be left blank in order to send mail via PHP's mail() function. I just installed the latest version 1.4.2 and it no longer seems to work.  Has support for this been dropped or am I doing something wrong?

Support for PHP's mail() function was removed in version 1.3. Please see https://github.com/roundcube/roundcubemail/issues/5340

I guessed as much but was unable to find anything via google search, in the docs or in the config comments.  Thank you for the link!

I understand that it does not make much difference now but just for completeness removal of PHP's mail() function was included in the release notes for 1.3 see https://roundcube.net/news/2017/06/26/roundcube-webmail-1.3.0-released and https://github.com/roundcube/roundcubemail/releases/tag/1.3.0
