As I get some errors when adding/modifying distribution lists and tampering with the user accounts (slapd crashes, 99% CPU usage), I plan to make a version upgrade of my zimbra server from 4.5.6 to 4.5.9, hoping this will help fixing them. The question is whether the pyzor and razor settings I made (for antispam, as suggested in the zimbra wiki) will be kept or if they'll be lost. I'm using FC6 and RHEL4 Zimbra packages (zimbra was installed using the wiki for installing zcs on FC6 64bit and addapting it for 32bit CPUs). Is there any issue of stability using this combination??
