Interesting, I've only played with courier before, and that involved a LOT more work, this looks great!  Thanks for the info.

One other question I was having about this barracuda, it seems to be having trouble with rate limiting and the messages are trickeling through abotu 1 every 2 hours instead of instantly.  If I can figure out how to sort out that, I'll probably be looking at rolling this out for a couple of our smaller domains today.

I have mynetworks set properly AFAIK in main.cf, not sure if there is somewhere to 'whitelist' the IP addresses (or host names) of my barracuda firewalls or what I need to do.

That was actually my fault, I had a mistyping in the mynetworks, going little stir crazy after staring at it all day I guess, it works great now, goign to do a little testing with this sieve and look at moving a domain or 2 over this afternoon.  If all goes well, we are definitely going to be purchasing the admin-pro, looks very impressive.

One last question I have is about 3rd party provisioning.  We have a billing system setup, if they want to create/delete accounts and domains through that, what would be the best method for them to connect to the server to provision the accounts. Had previously had it setup with virtual domains on SQL and it just executed the SQL statements to create the accounts as needed.

Ohh yeah, and I guess I need to find how to make it so when a new account is created in iRedMail I can add a folder called "Spam" automatically to the mailbox

well, got fileinto working very well, but only into existing folders

must have an error in my syntax somewhere

1     require ["fileinto"];
2     if header :contains "X-Barracuda-Spam-Flag" "YES" {
3       fileinto "spam";
4     }

Works great using the validate tool that was linked on the page you linked me: http://libsieve-php.sourceforge.net/

1     require ["fileinto"];
2     if header :contains "X-Barracuda-Spam-Flag" "YES" {
3       fileinto :create "spam";
4     }

However pukes with error:
Result: line 3: tag where string expected near :create

So, I'm obviously not using this :create tag correctly.  Just can't find good details anywhere on the internet about it.

dovecot 1.2.9

it doesn't seem to create it at all.  WHen setup with the configuration I have in the first example, if I replace the "spam" with the existing "junk" folder it works, but it doesn't create teh spam folder.

I tried logging out and logging back into web mail as well as closing and opening an IMAP client (thunderbird) and the mail was just gone.

I am using the most current iRedMail installed on a fully updated Ubuntu 10.4 LTS install.

And I double checked and mail plugs does have 'autocreate' in the dovecot.conf file

the log for sieve even shows the following line when I send a test message:

Info: sieve: msgid=<AANLkTimsX2qrn6mtJOVuum1p5CpCr_MVxC=EkrEQ5+WO@mail.gmail.com>: stored mail into mailbox 'Spam'

you are correct, of course.

Is there a way to have new folders subscribed by default in roundcube?

I'll read that tomorrow, last thing I did tonight seemed to work for the webmail side, which was change a line in main.inc.php to include

$rcmail_config['default_imap_folders'] = array('INBOX', 'Drafts', 'Sent', 'Junk', 'Trash', 'Spam');

Now the folder shows up in roundcube, I'll read up on that link though.

This is important for a couple of reasons, but I'm glad to see it seems to work now, that's a huge hurdle for me.

yup, that autocreate works brilliantly.

Set 'mail_debug = yes' in dovecot.conf, and monitor its mail log: /var/log/dovecot.log.

Just an update.  Just went live with the server a couple hours ago after some extensive testing.  If this goes well for the next couple weeks, we'll be looking to deploy iredmail for our customer server once the mysql iredadmin-pro is available.
