[Dovecot] Telephone systems and Dovecot

[Jonathan Knight]

Hi folks,
We're looking to integrate our telephone system with our email system.  
The telephone system will use IMAP4 to store WAV files in a users 
mailbox and then retrieve them for playing if necessary.  This is 
usually called "unified messaging".

The manufacturers are claiming full integration with Microsoft Exchange 
and Lotus Notes using IMAP4 and a single username and password to access 
all the users mailboxes.  I can see that Dovecot has a master user 
feature that looks like it will do the job.

Has anyone had any experience of using dovecot as a unified message 
server for a telephone system and has anyone any experience of 
configuring dovecot so that an MS exchange IMAP4 client using a master 
user can use dovecot without changing the client?

Jon.
