rc.d/dovecot allows for multiple concurrent dovecot setups, but in doing

so runs the dovecot binary against each provided configuration file to
obtain configuration data. When the configuration file doesn't exist, it
says:
	doveconf: Fatal: open(/im_not_here) failed: No such file or directory

Mistyping the conf file locations when doing multiple instances deserves
an error message. The real issue here is that in order to set up
dovecot, you have to actually copy files over from ${EXAMPLESDIR}. The
default configuration file intentionally does not exist in a clean
installation. So everybody who installs the dovecot2 port and does not
configure it will receive that message at every boot.

Fix it with a patch from pi that makes sure the conf file exists before
trying to do stuff with it.

PORTREVISION bump.
