Foolproof? Feh!

Took me a while to work out this malarky.

My setup involves users accounts stored in MySQL which exim uses to validate
accounts, before passing them to this router:

virtual_delivery:
  driver = pipe
  command = "/usr/cyrus/bin/deliver \
        -m ${substr_1:${local_part_suffix}} \
        -- ${local_part}"
        return_output
        user = cyrus
        group = mail
        log_output
        message_prefix =
        message_suffix =
        envelope_to_add = true
        return_path_add = true


I found it somewhere on the net and all I can say is it works for me!

You need to copy one of the suggested configs to /etc/cyrus.conf and then
write an /etc/imapd.conf file

Exim has support for pam if you compiled it in. My Exim setup checks the
passwords direct against MySQL, bypassing pam.

Relevant snippit of /etc/imapd.conf :

cleartextloginpause: 5
autocreatequota: 10000
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

Then configure pam as appropriate. (I'm using pam_mysql but I think I'll be
moving to pam_nssmysql sometime in the near future)

I've also got my init script to start/stop exim/cyrus/saslauthd all
together.


HTH & Good Luck!
Mark.
