I noticed the managesieve plugin stopped working with mail-client/roundcube-1.2.3 and dev-lang/php-7.0.15. The error appeard in /var/www/<webhost>/htdocs/roundcube/logs/errors as [07-Mar-2017 07:40:32 UTC] PHP Fatal error: Uncaught Error: Class 'Net_Sieve' not found in /var/www/<webhost>/htdocs/roundcube/plugins/managesieve/lib/Roundcube/rcube_sieve.php:65 and was predicted in "PHP7 Compatibility" on https://github.com/roundcube/roundcubemail/issues/4836 I can be resolved by installing dev-php/PEAR-Net_Sieve. Would be nice to have this in RDEPEND, thanks!
It's always been in the RDEPEND.
