 You never told us what's redirected to the imq device.  But I suppose it's
 incoming traffic from the internet.  If you want to match mail coming from
 the internet to your smtp server, you need dport 25.  All traffic is sended
 to your smtp and that's server is running on port 25.

 You connect to port 25 and it's for traffic leaving the server, so you need
 sport 25.
