I need to make the IMAP interface of an Exchange 2000 server available on the net, however I would like to give it a little protection, and believe Dovecot's IMAP proxy might be appropriate.
Does anybody have a *really simple* config that would allow IMAP pass-through to a single Exchange server?
The examples I've seen all assume some sort of load balancing, which isn't an issue here, so I'd like to eliminate the need for an unnecessary database server.
Does Dovecot do any cleanup of the IMAP commands that would be useful in protecting Exchange (from this, http://www.cvedetails.com/cve/CVE-2007-0221/ for example), or am I barking up the wrong tree?
If Dovecot isn't helpful for this, can anybody point me to a better resource?
An Exchange 2000 server is ancient. I wouldn't waste time with it unless there was no possible way to get an updated version; ie, Exchange server 2010.
The client won't pay for an Exchange update just to support a handful
of external IMAP users.
It works perfectly well internally, using a Postfix relayhost.
