Well I didn't get any replies on this one!
I guess no-one is using postfix as the MTA in a TruCluster.
However the folks at postfix-users were able to help, and I was able to
verify that postfix works fine in a TruCluster when using the 'flock' file
locking option.

Thanks Wietse,
That works very well. I've verified that flock works perfectly in
preventing concurrent delivery to mbox from different cluster members, as
well as locking out impad and popd :)
Postfix is great.
