Re: Migrating from qmail to exim question
[In reply to]
I installed courier-imap and courier-imap-auth.
My question is:
where do I configure exim and courier-imap to work together. what setting
do I need to configure on exim.conf file. Also openldap server runs on an
external server how to I tell exim to use it so that users can
authenticate through their e-mail clients using IMAP and their network
also when I sent my self a test e-mail using just exim right after I
installed it, it places the e-mail under /var/mail/$USER instead of
creating a Maildir folder for the user.
Thanks for your help.
