server to store the data in.

- Mailparse. Efficient parsing of email requires this extension.

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

- Sphinx Search. A client for the sphinx server, an alternative
|

to MySQL or Postgresql fulltext search. You will also need a

Sphinx server to serve the search queries.

You will almost definitely get 2-3 times better performance from your

Sphinx
|
||||
------
|
||||
|
||||
To use a Sphinx server to search users and notices, you also need
|
||||
to install, compile and enable the sphinx pecl extension for php on the
|
||||
client side, which itself depends on the sphinx development files.
|
||||
"pecl install sphinx" should take care of that. Add "extension=sphinx.so"
|
||||
to your php.ini and reload apache to enable it.
|
||||
|
||||
You can update your MySQL or Postgresql databases to drop their fulltext
|
||||
search indexes, since they're now provided by sphinx.
|
||||
|
||||
On the sphinx server side, a script reads the main database and build
|
||||
the keyword index. A cron job reads the database and keeps the sphinx
|
||||
indexes up to date.
