Hi bangsters-
The post seems to have disappeared.

However, any notion that Zimbra uses TEN times more resources is ludicrous.

I would venture to say that the resource usage would be less because if you install Exchange on a Windows server, you get all of the wonderful services that come with windows and exchange. Not to mention the gui itself. Oh, and we can't forget about virus protection either.

On a linux Zimbra box, you've got wholesome ingredients like:
mysql
postfix
clamav
amavisd
java


add a dash of salt, let simmer for an hour, then serve warm.

Hi bangsters:

I have 3 mail servers. The first in exchange 2000 and second in linux with centos 5 and zimbra 5.0 and third centos 5.0 with zimbra 4.5.7. My users in exchange is 650 and my users in linux 5 users by server. Zimbra 4.5.7 is slow but in 5.0 rc1 is more fast.
I suggest to install zimbra 5.0 test this version. But in test environment not in production. I seriously think to migrate to zimbra 5.0 because is more fast, my ram in my server is 1.0Gb. only to add to 2 GB.
it is true. zimbra use more resources, but is a powerful tool and our goal is to help that zimbra will be more fast.

I'm really not sure we're measuring apples to apples here.

A windows system service is not the same as a posix system service.

If it were true, then (judging by the ten times rule above), then Zimbra's requirements would have to be 20 GIG RAM.

Zimbra recommends 2GIG. I ran a server for 3 years with 200 people on it with 512 MB (ZCS 3.1-4.5.6).

It may well be that Zimbra uses more "resources" than exchange, but the TEN times claim simply is not true.
