worked well. It is also possible to run MySQL 5.5+.

recommended and also some variant of 'suexec' (or a

proper setup php-fpm pool)

Submission by email or SMS-over-email uses this.

Sphinx server to serve the search queries.

- gettext For multiple languages. Default on many PHP installs;

- exif For thumbnails to be properly oriented.

You may also experience better performance from your site if you configure

a PHP cache/accelerator. Most distributions come with "opcache" support.
