Humm ? I never had to build any tools.

For courier-imap itself, of course. As far as I know, there is no other
way to make courier-imap work.

Are we talking about exim or postfix ?

If you are using postfix, then it does make send to use vpopmail.
I'm not saying otherwise.
My point is only regarding Exim.
The thing is, many people don't realize that, when configuring exim
to use mysql, you write the SQL queries on the configuration file, so
you can pretty much do anything you want, even get data from multiple
tables. Also, you can put SQL lookups everywhere, even on the ACLs
(most specially on the ACLs), giving you a very good degree of flexibility.
Also, keeping everything happening inside exim, you make things much faster.
You don't have to keep forking new processes (which is costly for the OS),
and memory allocation is much smarter.
As I said, I don't have anything against vpopmail or maildrop. I'm just
against using those with Exim. If you are using something else (sendmail,
postfix, zmailer, qmail, whatever), you are very welcome to them.
