Upgrade Fedora 10 packages

Recently I got to upgrade some packages of the my server which runs on Fedora 10. However I also got to know that Fedora 10 repo are not more maintained. Therefore I searched for some other repo and found a repo called remi. Using which I could upgrade my packages. Here are the steps that I followed :

rpm -Uvh
then I could update the php packages by executing following command :
yum --enablerepo=remi install php-pear php-pdo php-mysql php-pecl-memcache php-gd php-mbstring php-mcrypt php-xml

Control spamming through Horde webmail

There are ways that you can use to control spamming through Horde web mails :
Few of the configurations are as follow :

You need Horde 3.2/IMP 4.2 or later!

1. Turn on $conf['user']['verify_from_addr'] in Horde 3.2. This will
prevent a user from changing their from address without an email
confirmation - not a hard road block to a throwaway hotmail address,
but another hoop to jump through. Also useful for policing your legit
but perhaps less-than-technical users.

2. Turn on the sentmail logs in IMP 4.2. The driver and the amount of
time logs are kept are configured under "Other Settings" in IMP's
config (or $conf['sentmail']). Once you turn on the driver, there are
two permissions you can set through the Horde permissions API:

'imp:max_recipients' => "Maximum Number of Recipients per Message"
'imp:max_timelimit' => "Maximum Number of Recipients per Time Period"

The first one is a hard limit on the number of recipients for a single
message. The second one is limit on the number of messages that can be
sent in the time period configured in $conf['sentmail']. This is for
preventing someone from sending to exactly the max # of recipients
over and over again.

How to do this :

do it in the horde config file

2 :
Administration -> Permissions -> then add sub permissions to IMP
