I need know how to perform a update on all softwares included on zimbra pack. For example, i found here an tutorial about how to upgrade the clamav software:
Updating CLAMAV - Zimbra :: Wiki
But, i need upgrade ALL softwares used by zimbra, like spamassassign, amavisd, mysql, cyrus-sasl, openldap and postfix.
I'm asking about it, reminding the security fix on posfix and other softwares.
If today was announced a urgent patch to fix some serious security bug in one of these packages, how can I apply this patch?
Whereas sometimes there is no patch, but a new version with the bug fixed. How can I do this upgrade?
This is a very serious matter that the team zimbra should take into consideration.
