	Build recipient lists for three types of e-mail:
	(a) Error Reports, (b) Package Updates, (c) Help requests, generated by
	lonerrorhandler.pm, CHECKRPMS and lonsupportreq.pm respectively.

	Inputs:
	defmail (scalar - email address of default recipient),
	mailing type (scalar - errormail, packagesmail, or helpdeskmail),
	defdom (domain for which to retrieve configuration settings),
	origmail (scalar - email address of recipient from loncapa.conf,
	i.e., predates configuration by DC via domainprefs.pm

	Returns: comma separated list of addresses to which to send e-mail.
