dovecot - Feb 2011 - help with dovecot installation dependencies

I'm on RHES 4.x

I downloaded 2 dovecot RPM packages from
 http://packages.sw.be/dovecot/

dovecot-1.0.13-1.el4.rfx.i386.rpm       13-Nov-2010 22:15  1.8M  RHEL4 and
CentOS-4 x86 32bit
   and
dovecot-0.99.13-1.2.el4.test.i386.rpm   21-Feb-2005 16:57  693K  RHEL4 and
CentOS-4 x86 32bit

The first rpm fails with error below :
# rpm -i ./dovecot-1.0.13-1.el4.rfx.i386.rpm
warning: ./dovecot-1.0.13-1.el4.rfx.i386.rpm: V3 DSA signature: NOKEY, key
ID 6b8d79e6
error: Failed dependencies:
        libmysqlclient.so.14(libmysqlclient_14) is needed by
dovecot-1.0.13-1.el4.rfx.i386

I have a hard time trying to locate an rpm that contains
libmysqlclient.so.14
& have no luck :
# rpm -i ./mysql-libs-5.1.42-4.el6.i686.rpm
warning: ./mysql-libs-5.1.42-4.el6.i686.rpm: V3 RSA/MD5 signature: NOKEY,
key ID f21541eb
error: Failed dependencies:
        libcrypto.so.10 is needed by mysql-libs-5.1.42-4.el6.i686
        libssl.so.10 is needed by mysql-libs-5.1.42-4.el6.i686
        rpmlib(FileDigests) <= 4.6.0-1 is needed by
mysql-libs-5.1.42-4.el6.i686
        rtld(GNU_HASH) is needed by mysql-libs-5.1.42-4.el6.i686
        rpmlib(PayloadIsXz) <= 5.2-1 is needed by
mysql-libs-5.1.42-4.el6.i686


Then I installed the 2nd dovecot rpm successfully but its filename indicated
it's a "test" version :

# rpm -i ./dovecot-0.99.13-1.2.el4.test.i386.rpm
warning: ./dovecot-0.99.13-1.2.el4.test.i386.rpm: V3 DSA signature: NOKEY,
key ID 6b8d79e6

# /etc/init.d/dovecot start
Starting IMAP daemon (dovecot):                            [  OK  ]


Q1:
Is the test version rpm  of dovecot reliable?  It's only half the size of
the other rpm (that I was not able to install)

Q2:
Kindly assist me to resolve the 1st rpm issue : let me know where I
can download the dependencies etc


Q3:
Lastly, kindly point me to a simple doc that tells me how to
do basic setup of dovecot & create simple mailbox accounts. I'm a
 complete newbie to dovecot & postfix.  Have some Linux know-how

0.9 / 1.0 : These versions are way out of date and you will probably
have a hard time getting support. I suggest you try the current
versions from atrpms.net We have been using the 2.0 RHEL5 packages by
Axel Thimm for quite some time now and they work flawlessly. 

Link for RHEL4 packages: http://packages.atrpms.net/dist/el4/dovecot/

Maybe this fixes Q2 as well ;-)

Q3: You'll find lots of examples / tutorials in the dovecot wiki :
