A few words of caution... Old employee mailboxes were once legitimate.
This means that they may get legitimate messages - so you must be very
careful... It's good to let these go for a good long time before
putting them in place as any kind of spamtrap... You also want to
avoid creating a spamtrap than anyone can easily predict because it
can be poisoned.

That said, if the traffic in these accounts is all spam - then they
are good candidates.

In our system we will review every message that gets past the filter
so you should be safe if the occasional legitimate message shows up -
that will just force us to use "abuse" rules rather than spamtrap
rules.

Another thought about the nobody alias. We've had some experience with
this--- having set up the nobody alias on a few systems and then
watched them fill up with dictionary attacks, we were then able to
turn on a few specific addresses from the attacks as spamtraps and
turn off the nobody alias.

If you keep the nobody alias on you will most certainly see a growing
spam load - you may not want this.

Here's a helpful reference.
