Webmail: Compress static resources.
We leave dynamic pages (those passed to PHP-FPM) alone for now:
compressing them would make us vulnerable to BREACH attacks. This will
be revisited once Roundcube 1.5 is released: 1.5 adds support for the
same-site cookie attribute which once set to 'Strict' makes it immune to
BREACH attacks:
