I know this is hard and probably common, but..

im trying to run a mail server for pop/imap/smtp, etc
I've sifted through hundreds of tutorials, etc, with no success.

I have Fedora Core 3 installed, and updated with yum.
I have Postfix installed, with MySQL. TLS and SASL included
I have Cyrus IMAP installed
I have MySQL installed
I have Postfix Admin installed and working

Now, these all seem to be working properly, all running, no errors.
I can connect from a windows box using pop or imap and it will connect, but I can not authenticate - this seems to be my problem. I dont have a great understanding on ciphers in linux -

Heres some lines from my config files:

-- config.inc.php (Postfix Admin) --
$CONF['encrypt'] = 'md5crypt';

-- \etc\imapd.conf --
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

-- \etc\sysconfig\saslauthd --
MECH=pam

-- \etc\sysconfig\saslauthd.postfix --
MECH=pam

-- \usr\lib\sasl2\smtpd.conf --
pwcheck_method: auxprop
auxprop_plugin: sql
sql_engine: mysql
mech_list: PLAIN LOGIN
sql_hostnames: localhost
sql_user: postfix
sql_passwd: postfix
sql_database: postfix
sql_select: SELECT password FROM mailbox WHERE username = '%u@%r'

I can authenticate using POP to the root user and his password, but not with IMAP...

Any help would be much apreciated, if you would like more on my config please ask.
