We're using a sonicwall NSA2700 in High Availablility state.

We haven't been able to find anything wrong with how MDaemon is binding to an IP yet, but we are still testing. What type of firewall are you using?

If you uncheck "Enable outbound IP binding" and "This domain recognizes only connections made to these IPs" for both domains, what happens? Does the OS choose the desired IP? No change after makin...

It is,  and has been bound (see screen shot below).  Also, looking at what is actually bound please see the output of netstat -an (below).   TCP    192.168.21.251:25 &nbs...
