Is this even a supported configuration? I've never heard of anyone doing  
this.    
   Why not?  
    
           From dovecot WIKI:  
  
The destination servers don't need to be running Dovecot, but you should make sure that the Dovecot proxy doesn't advertise more capabilities than the destination server can handle. For IMAP you can do this by changing   imap_capability setting. For POP3 you'll have to modify Dovecot's sources for now (  src/pop3/capability.h). v1.2.rc4+ automatically sends updated untagged CAPABILITY reply if it detects that the remote server has different capabilities than what it already advertised to the client. Note that some clients simply ignore the updated CAPABILITY reply.  
  
   
  Dovecot proxy is intended to act as a proxy between multiple *dovecot*  
servers...  
  
But, I'll be interested to hear Timos response, if this might actually  
work...
