I have a HA Zimbra installation at a client, running Heartbeat and DRBD to mirror the boxes. The primary one is a dedicated server and the secondary is a VM on a XenServer, just in case things go pear shaped.
The client used to have Mailscanner in front of an Exchange server which I trashed at the earliest conveniece. ;-)
However, now that they are just using Zimbra, the client is starting to miss the additional functionality that Mailscanner gave them, being able to release mail and better manage spam-filtering and better reporting.
After seeing some posts dating back to 2006, I would like to enquire about 3 things (in order of importance):
1) any success in installing mailscanner on the same box as Zimbra? As the client need absolute mail reliability, we already have 2 servers running HA for Zimbra and I'd hate to have to add another 2 (for fail over) if I want to add Mailscanner. So to get a way to install mailscanner on the same box would be just perfect.
2) Is there any better silimar spam/reporting/management utilities for Zimbra in the pipeline?
3) Is there a better reporting facility, like a log of mails sent/received, mail volume per user per day, etc.etc. without a manually parsing through the logs on a per-user basis? If the worst comes to worst, I'll have to write a Windows app that parse the Zimbra logs...
