The answer to your answer is qiute simple. I have to have a stable mailserver.
But I've tried some of your examples befor I wrote the post to the list. I've
tried to authenticate qmail and courier against Mysql. First problem: You have
to heavily patch the qmail sources with a patch that isn't developed anymore and
has some limitations. Second: The performance was not acceptable at all, because
the latency of the db. Next reason was: qmail has it's own db format and so I can use stable and reliable software as a
smtp daemon. As well as I think courier is. It may be a feature request to
courier, because as I think courier is the most compatible IMAP daemon for
qmails maildir. I've found patches for cyrus IMAP to authenticate via cdb file,
but then I've got my old problem of patching reliable software to maybe
unstable.

But I thank you for your remarks.

Wouldn't it be easier to just use qmail with Berkeley DB or GDBM or LDAP or
MySQL instead? Why do you need to use a DB that Courier doesn't support when
there are so many choices of DBs that it will support?

Hi folks,

has anybody some information about authtenticating users agaist a cdb file.
I've searched the mail archives and found not post on this topic. I try to
realize a mail cluster with smtp, po3 and IMAP. Smtp and pop3 I realized with
qmail and cdb a database, but Courier unfortunately has no cdb support. I used courier-imap in a claasic configuration and I'm very confident with
it. Now I want to know wheter there is any possibility to auth user against a
cdb database, because I don't want to change the IMAP server.

Thanks
