Hm, the man page say "bracket-enclosed IP address" but until now we  
have only used the port as service name "imap" e.g. listen="imap"  
which works fine for both IPv4 and IPv6 on a dual stack host. Do you  
have any special need to use the hostname/IP address and not bind to  
all local addresses?
