In normal operation, Postfix makes a system call to check to see if it can
create a file of a certain size. Inside a jail, this call will not succeed as
per the very design of jails. Thus, you must use the following one-line patch
to make postfix work. You can use the `patch` command, but it's probably just
easiest to insert the line manually. Remember that a 'make clean' from within
the port directory will wipe this change out, patch or no.

This patch probably hasn't made it into the port because it completely
bypasses a moderately important check. As long as you keep a close eye on disk
space, you should be okay.
