if both
postfix servers were used at the same time? (i.e. load balanced)
In fact I may be able to answer my own question by saying yes, it
would cause
a problem as you're not supposed to write to a DRBD secondary...
I saw some active-active DRBD howtos; but they used filesystems
likeOCFS2 or GFS
and such...

But I am no expert...

If I used a nfs cluster, I could use both postfix server at the same
time, couldn't i?
these questions you should really ask in the heartbeat/drbd mailinglist(s).
Just one hint: think about complexity in an active-active cluster
running ocfs2 and mail. Think about file locking.
Building this is one thing. Managing the unexpected afterwards is
another thing.
