Hi,
There were three products which look promising, we will probably be going with one of these in the near future:
Email Systems <www.emailsystems.com>, externally provided archive solution, using SMTP based archiving, sees no reason why it won't work with Scalix, as long as it can deliver archive messages via SMTP.. This is the one we will probably go for, if we get sign off we will get a trial at which point I will give feedback.
Cryoserver -
http://www.forensiccs.com/. This is an appliance and the guys there have dealt with Scalix previously.
Message Solution -
http://www.messagesolution.com - Is a bit cheaper than the other products,, and receives SMTP journeling from Scalix.
CA have a solution, but it looks very complex and time consuming to set up and manage.
We want to get users using this as their long term storage, so they can delete messages out of their mailbox say after a month. Authentication iss an issue for us, since we don't use Active Directory on the server.
Andrew.
