As David already mentioned, the php file_upload_size might need some 
tuning. (OTOH, one mailbox means somewhat between 50 and 100 byte in 
CSV, so you'll at least have 2000 mailboxes in 1 MB CSV file. That's a 
lot already ;-)

Another setting that might hit you is the max_execution_time. (You can 
work around it by doing a self-redirect after creating 50 or 100 
mailboxes with ?csvfile=uploaded_file.csv&continue_with_line=51)

You can tune both settings in your PHP configuration, so this shouldn't 
be a real problem.

You might also want to consider the command line client instead of the 
web interface for mass creation of mailboxes.

Most important: Please use the MailboxHandler class (see below for 
details).

create-mailbox.php and edit-mailbox.php are dead code (in maintenance 
mode) and will be deleted sooner or later. Please don't add new features 
to one of those files.

Another important thing is to base your changes on SVN trunk.


At the moment, using MailboxHandler means something like:
   $handler = new MailboxHandler($address);
   if (!MailboxHandler->add($password, $name, $quota, $active, $mail)) {
       die ('creating the mailbox failed - ' . $handler->errormsg);
   }

$address is the username / mail address
$password should be obvious ;-)
$name is the realname / comment / whatever
$quota means quota in MB
$active is usually just   true
$mail means sending the welcome mail and also should be   true

See scripts/shells/mailbox.php -> AddTask -> __handle() (part of the 
command line client) for a working implementation that uses this class.

Whenever I have some time [1], I'll update MailboxHandler to use the 
function names etc. I'm already using in DomainHandler and AdminHandler 
(see edit.php for working implementation). This means you'll need some 
small changes in your script on how you call MailboxHandler, but that 
will be quite easy.

[1] If you want to update MailboxHandler to be based on PFAHandler, of 
    course nobody will stop you ;-)
