Since i cannot post a bug on the bug tracker (registration disabled), i try here. I'm using the git master version and i met this error on the postfix.log

This happens only when i try to send an email with roundcube...

Consider i'm using the PHP 7 with Apache 2.4...

For PHP7 you need Roundcube 1.2.

As I said i'm using the github version of roundcube (the last one, 1.2-git)...

Besides both "sendmail.inc" files (from the 1.2 released on november and from the 1.2-git) match, so the error doesn't change...

Most likely you didn't install dependencies (/vendor directory). As for the session error this is your php installation issue. Looks like php can't write to /var/lib/php/sessions.

Ok resolved, i forgot to enable the session module for PHP xD
