Anyway....why isnt the package of squirrelmail 1.4.5 in the repository? where can i find a description of the packages in the repository..i mean...how can i know the real version..the patches applied to it..and etc. Is there a way to use yum only to fix security problems? or that is what it really do and i dont know it yet...the first time i run yum update..i download a lot of packages..but how can i know if they are new version or just security patches for my old ones...? If i regulary use the yum update should I be relax that I have all my packages up to date and with their security patches? Thanks
