Hello Firas,

Yes, unfortunately, the documentation on how to setup cyrus-imap is a
bit scarce. That's one of the reasons I would advise you to dump
cyrus-imap in favor of Dovecot. Unless of course you have to use
cyrus-imap for whatever reason. We've switched from cyrus-imap to
dovecot for our small site (~3000+ email accounts) and it's working
like a charm. Just thought I'd let you know about an alternative.

Now, going back to your cyrus-imap problem. It looks like you don't
have any authentication mechanism in place. Have you install
cyrus-sasl and cyrus-sasl-saslauthd ? If you haven't then you probably
should. That's the way we had it working anyway. Here's my *very*
brief notes on the topic:

1-- Install the cyrus-* ports.

2-- Configure sendmail to use SASLAUTH. These are the lines related to
cyrus in my /etc/mail/`hostname`.mc file

dnl # The AUTH mechanisms. See 24.9.5 as AuthMechanisms.
dnl # For information on SASL, see 3.4.48 and these URL:
dnl # http://www.iana.org/assignments/sasl-mechanisms
dnl # http://www.sendmail.org/~ca/email/mel/SASL_info.html
dnl #

dnl # confLOCAL_MAILER
dnl # Define what is the local MAILER.
define(`confLOCAL_MAILER', `cyrusv2')dnl

dnl # MAILER
dnl # Setup various mailers.

3 -- Make sure imap without SSL is running from
/usr/local/etc/cyrus.conf.  For some weird reason, I can't run cyradm
over TLS.

If you disable imap without SSL, you won't be able to login via
cyradm. That was one problem I had and was not able to fix this. So I
used pf to block all comms to the imap port unless it's coming from
the localhost or the admin machines in our LAN.

4 -- Add the cyrus administrator's user & password.

sudo saslpasswd2 cyrus

5 -- Create users. Here you must make sure your
/usr/local/etc/imapd.conf has unixhierarchysep set to no (or
comment-out). Otherwise you'll run into trouble if you use usernames
such as david.robillard (i.e. the dot seperator).

sudo su - cyrus
cyradm localhost
cyradm> cm user.username
cyradm> exit    # return to user cyrus.

6 -- As the cyrus user, set a password for user username

saslpasswd2 username

7 -- Test the setup using IMAP over SSL.

imtest -v -a username -u username -s localhost

NOTE -- Deleting a Mailbox or Removing a User
NOTE: Administrators do not have delete rights on mailboxes by
default. So you must give yourself the right to do so before trying to
delete the mailbox.

sudo su - cyrus
cyradmin localhost

localhost> sam user.johndoe cyrus all
localhost> dm user.johndoe

There, that's about what I can tell you about this. Now you have a few
changes to do in syslog.conf(5). Here's how I've configured mine
(those are the LAST lines in the file)

*.*                                             /var/log/saslauthd.log
*.*                                             /var/log/cyrus.log
*.*                                             /var/log/cyrus.log
*.*                                             /var/log/cyrus.log
*.*                                             /var/log/cyrus.log
*.*                                             /var/log/cyrus.log
*.*                                             /var/log/cyrus.log

Then tell newsyslog.conf(5) about these files.

/var/log/saslauthd.log                  640  5     1024  *     J
/var/log/cyrus.log                          640  5     1024  *     J

Of course, you must change rc.conf(5) too:

cyrus_imapd_enable="YES"        # Enable imapd(8).
cyrus_imapd_flags="-d"                # Flags to imapd program.
saslauthd_enable="YES"             # Enable saslauthd(8) (or NO).

If you need more detailed info, I can send you my cyrus.conf(5) and
imap.conf(5) files. As you can see, it's quite a lot more complicated
then with Dovecot :)
