Uh? Are you really sure? Which version of cyrus do you use? Cyrus'
installation are not platform dependant and I have only seen the skript
versions so far..
Anyway, here is a (very tiny) example how to do some stuff on the
server. It simply adds all users supplied by STDIN:
#!/usr/bin/perl
use Cyrus::IMAP::Admin;
my $client = Cyrus::IMAP::Admin-new('localhost');
$client-authenticate(-mechanism, login, -user, admin, -password,
adminpw);
while () {
chop;
$client-create(user.$_);
}

Re: What File Types does Cyrus use?
The .index, .cache, ... files are Berkeley DB files, I believe (www.sleepycat.com). I'd also like to know more about what's stored where and how, so that our webmail app can use them directly rather than going through the IMAP server to speed things up. - Original Message - From: Ashley Breeden [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, November 22, 2001 1:11 PM Subject: What File Types does Cyrus use? Hi All, I have been trying to find this answer out for days. I am writting a perl script for use with our Cyrus POP3/IMAP4 server and I need to interigate the Cyrus.index. Cyrus.header, Cyrus.cache files. However I have no idea what type of files they are? Does anyone know How I can find out or what the will be. If I use file cyrus.header I get cyrus.header: data As you can see that doesn't give me a lot to work with. Also if possible does anyone have anything that explains how each file is layed out, by this I mean what data is stored and for what. Thanks heaps! Ashley Breeden

Otherwise I'll just work it out for myself by looking at the code, but that seems awfully inefficient, and will mean I'm just more likely to muck something up...
