thank you for the pointer. I must have overlooked it.
On a side note, I would like to exchange some opinions with you regarding mysql replication and holding accounts in real-time db.
I was wondering if it won't be a much simpler setup to just use db3 files for accounts (postfix/courier) and just rehash them when necessary on all involved servers.
Currently all accounts are in mysql and postfix is reading directly there. I have some concerns on issues with mysql availability (specially on heavily loaded servers).
On such servers (perhaps running web+mail+dns) a failure of the mysql server will bring all the system down.
If db3 files are used the mail/pop/imap setup will be much more stable and perhaps efficient.
postfix restarts automatically every time it detects a change in an external hash table.
On the other hand I known mysql toasters can be very very reliable. I have one with some 1000 accounts on it that was installed in the woody era and has since been upgraded several times: it's rock solid but again it's a dedicated machine and is a pure toaster. No joomla sites to hog the mysql db.
Not trying to steer development here... just interested in your opinion.
