dovecot - Jan 2015 - Proxying when src and dest on non standard ports

Hello,

I want to test dovecot proxying, on a user basis, in a simple set up (proxy, no
proxy_maybe and forward the passwd to the remote server).  This seem pretty
simple except that, in order to test it alongside the production server, I set
up 3 servers :

  . the proxy, listening to pop and imap on non standard ports 9143, 9993, 9110,
9995
  . a proxy destination for some users, listening on 10143, 10993, 109110, 10995
  . another proxy destination for some other users, listening on 20145, 20993,
209110, 20995

But there seems to be only one 'port' extra_field, so how can I handle
the
proxying of both IMAP and POP3 (especially for the same user who can use both)
?

Thanks.
