  On some systems, in particular on Solaris, you will need to rebuild  
the Horde locale files. You may need to restart the web server after  
rebuilding the locale files in order for the web server to see the new  
files.

++++ Which database should I use?
+The one you already have, of course!
+
+Well, no, that's not exactly true. Horde 3 supports a wide variety of  
database backends. The database support in Horde 4 is more limited.  
The most stable databases to use with Horde are [http://www.mysql.com/  
MySQL] and [http://www.postgresql.org/ PostgreSQL]. Since they are  
free (and Oracle, MS-SQL, Informix and Sybase are not), they're the  
ones that get the most use by developers and by those installing IMP  
who don't already have a commercial RDBMS lying around. Choosing  
between !MySQL and !PostgreSQL is as much a religious issue as a  
technical one; !MySQL was traditionally considered to be faster but at  
the expense of robustness and providing commercial-RDBMS features,  
while !PostgreSQL was traditionally considered to suffer slightly in  
performance and ease of management while being more of an  
enterprise-class database. Recent versions of !PostgreSQL and !MySQL  
are probably of about the same performance. !MySQL is probably more  
popular however due to these historical circumstances and  
considerations.
+
+Those of you with existing Oracle, MS-SQL, Informix or Sybase  
installations will be happy to know that you can use them at least  
with Horde 3 as well. The only disadvantage to that is that it might  
require a little more work to configure, simply because it hasn't been  
tested to the extent that the free databases have. If you need support  
for one of these databases in Horde 4 too, consider  
[http://www.horde.org/services sponsoring the development] of  
additional database drivers for the Horde DB abstraction layer.
+
++++ Can I run Horde without a database?
+You //can//, but database functionality such as persistent  
preferences will not be available. We strongly recommend using a  
database with Horde.

  +++ Can I use POP3 instead of IMAP?
  **[IMP 4.x/5.x]:** Certainly! IMP supports IMAP and POP3; just  
specify the appropriate protocol for each server in  
{{horde/imp/config/servers.php}} resp.  
{{horde/imp/config/backends.php}} as described in the comments at the  
top of that file.

  Keep in mind that for IMP 4 PHP will //always// have to be compiled  
with the {{--with-imap}} option to {{configure}}, and built against  
the IMAP c-client libraries, even if you're not going to use it with  
an IMAP server.

  +++ Is Sendmail required?
  No, IMP can use either a local sendmail (compatible) program, or  
connect to a remote SMTP gateway. So if you have access to a remote  
SMTP gateway, then there is no need to install sendmail (or  
equivalent) on the webserver.
