Hi
I'm running ZCS 7.1.1 GA 3196.UBUNTU10_64 UBUNTU10_64 FOSS edition inside a Virtualbox VM.
The server has been running absolutely brilliantly since I installed in March.
However, recently I had some problems with my router (provided by my ISP) where my ADSL line kept dropping out so I had to change it for another router.
The router I changed it for was an original router I used to use and the IP addresses ranges and everything were set up just the same as the faulty router except for 1 thing and that was the IP address of the router itself. The faulty router (and therefore my default gateway on all my machines) was set to 192.168.20.254, whereas my replacement router was set to 192.168.20.1.
So, when this router change happened my ZCS stopped sending/receiving mail so I figured there must be the old .254 address somewhere in one of the config files. I went digging around and of course it was set up in BIND as a forwarder in named.conf.options.
I changed that IP to be 192.168.20.1, changed the serial number in db.<domain> (not sure if I needed to do this or not) and restarted BIND hoping this would fix the problem but it hasn't.
If I login to the webclient and try to send an email, when I click the 'Send' button it just sits there for a few seconds and then comes up with a 'Work In Progress' box saying 'The server appears to be slow to respond, and may be unavailable. Press the button to cancel your request.'
I can't see anything in any of the logs that looks like an error so I'm really confused as to what is happening here.
If someone could help me I would be VERY grateful.
I've attached the logs.
Here's my BIND setup:

// This is the primary configuration file for the BIND DNS server named.
