What I have done is patching uw-imapd to support plain-text passwords 
taken from a file in the users homedirectory. This imapd runs on the 
standard imap4 port. I did this by modifying the cram-md5 code in 
uw-imapd.
 
The reason for this radical decision to decrease security is mobile 
phones. It's quite expensive to do SSL on a mobile phone (batterywise).

Then we have another imapd that speaks on the imaps port. 

This combination works fine for us. So far :)

Well, mobile devices, such as some mobile phones don't do SSL/TLS, it 
has to do with the required hardware and available batterypower. Although 
the phone speaks some kind of imap...
