postfix check is called after all other checks have passed and, you're
right, it also checks the required directories.
i think i had some issues though:

but i cannot remember the exact problems anymore.
anyways, postfix check will return a "OCF_ERR_GENERIC"
which is regarded as a soft error (!) [1] and will
a. not hint the user or a gui application to the exact problem and
b. will lead to a restart of the failed resource on the same node
the more in-depth check will fail with OCF_ERR_INSTALLED [2] or
OCF_ERR_PERM [3] and will
c. give more information in this regard and
d. migrates the resource to a different node,
which makes sense if i.e. the "shared" queue directory (nfs, etc.)
isn't available.
i think that this behavior is good and checking the most commonly
modified directories separately has been very helpful in my setups.
but of course, i'm open for comments.

no worries. english isn't my first language either and until now we
managed to work things out, right? :)
