Hi,<br>
<br>
A bit more on securing a zimbra server:<br>
<br>
You should deploy a multi tiered approach as well with a Zimbra proxy server sitting in front of the main mailbox/mta server in its simplest form.<br>
<br>
You can then ensure that you have DKIM and SPF set up properly.<br>
<br>
Then in ZImbra web management, enable blocking of risky attachments (I block all the ones in the list)<br>
<br>
Although I have good success with the spam control in ZImbra, its important to train users to use the spam/not spam button to teach zimbra what is and isnt spam.<br>
<br>
I also use an Untangle Unified Threat Management Appliance infront of my zimbra to add extra phish, spam and virus cover to the mails and provide firewall and IPS.<br>
<br>
Hope that helps.<br>
<br>
Alex<br>

Hi,<br>
<br>
I presume you are using the FOSS version. What you want is not possible.<br>
<br>
In theory you could fork the source and compile yourself and then make the changes, but this will bring you much heart ache.<br>
<br>
In order to do what you want you must buy the Paid for Network Edition of zimbra.<br>
<br>
Do take a look at <a href="http://forums.zimbra.com" rel="noreferrer" target="_blank">forums.zimbra.com</a> for a lot of information, as this mailing list may not have too much.<br>
