Well it is a full RackSpace Dedicated server runing RHEL 6 - 64bit.
Dell Memory:  24 GB DELL RAM, GB Memory: 24
Dell Servers:  Dual Socket Quad Core Intel Xeon L5520 2.26GHz, #Cores per Proc: 4, #Processors: 2
Hard Drive:  146GB SAS 15K RPM Drive, HDD RPM: 15000, GB Hard Drive: 146
Hard Drive:  100GB SFF SSD Drive, GB Hard Drive: 100
Linux OS:  Red Hat Enterprise Linux 6

However I already migrated some 160 domains to this server so it is running several sites already. So I can not install it fresh because many opf my developers have already adjusted the older PHP scripts since we upgrated from PHP5.2 on the opld machine to PHP 5.3 on the new and this caused a lot of issues.
If you think you can install this without breaching my system you can try.

Best wishes,
thomas

Just one more note, I do relay on MuSql 5.5 and PHP 5.3.14 because we use very specific features that require these versions.
This is a server that has 150 domains running so I can not do a fresh install, I already did mess with it for 3 days and now asked the assistance of a senior rackSpace Administrator that tells me it can't run. So please let me know if there is a solution that lets me run this software without breacking my mission critical system.

Best wishes,
thomas

Well looks like this is going to be a problem. I actually had one of the provesional system administartors of RackSpace try this and here is his conclusion:

iRedMail depends on some packages, including mysql and php.
Since you are using mysql and php from IUS repository their names are mysql55 and php53u, it causes iRedMail installer to think that mysql and php is not installed on your system. In the next step it tries to install them and fails.

< INFO > Installing package(s): mysql-server.x86_64 mysql.x86_64 mod_auth_mysql.x86_64 httpd.x86_64 mod_ssl.x86_64 php.x86_64 php-common.x86_64 php-gd.x86_64 php-xml.x86_64 php-mysql.x86_64 php-ldap.x86_64 php-pgsql.x86_64 postfix.x86_64 policyd.x86_64 dovecot.x86_64 dovecot-managesieve.x86_64 dovecot-pigeonhole.x86_64 clamd.x86_64 clamav.x86_64 clamav-db.x86_64 spamassassin.x86_64 altermime.x86_64 perl-LDAP.noarch perl-Mail-SPF.noarch perl-Mail-SPF-Query.noarch amavisd-new.noarch python-ldap.x86_64 python-psycopg2.x86_64 python-jinja2.x86_64 python-webpy.noarch MySQL-python.x86_64 mod_wsgi.x86_64 awstats.noarch fail2ban bzip2.x86_64 acl.x86_64 patch.x86_64 tmpwatch.x86_64 crontabs.noarch dos2unix.x86_64 logwatch

Error: mysql55-server conflicts with mysql-server
Error: mysql55 conflicts with mysql
Error: mysql55-libs conflicts with mysql-libs

Obviously iRedMail is looking for packages with very specific names.

iRedMail documentation states that "iRedMail is designed to be deployed on a FRESH server system, which means your server does NOT have mail related components installed, e.g. MySQL, OpenLDAP, Postfix, Dovecot, Amavisd, etc. Otherwise it may override your existing files/configurations althought it will backup files before modifing, and it may be not working as expected. "

It seems that the only way forward with iRedMail is to either:
a) downgrade mysql to stock version
b) reinstall the server with a fresh copy of the operating system, then install iRedMail and then upgrade MySql/php/other to required versions. Please note that I am not sure how iRedMail will work with those packages.

I have tested iRedMail with mysql55 and unfortunately does not work. You will need to contact iRedMail devs to ask if it is even possible.

Please let me know your thoughts.

since I did not install iRebMail

Dear Thomas,

iRedAdmin-Pro requires the latest iRedMail, so please install iRedMail first, then install iRedAdmin-Pro.

I removed the symlink and renames the install from iRedAdmin-Pro-MySQL-1.4.0. to iredadmin.
I can now login but since I did not install iRebMail it did not make the vmail database so i get lots of errors that vmail tables are missing. Is there anywhere a .sql file that does make all tables for this database?

Best wishes,
Thomas
