This depends entirely on your local mail topology. If MIMEDefang is running on your MX hosts, there is a real social cost associated with stream-by-recipient. If MIMEDefang is running on an internal SMTP hub, then you've already accepted the mail anyway at your perimeter servers, and that cost goes away. -- Matthew.van.Eerde (at) hbinc.com 805.964.4554 x902 Hispanic Business Inc./HireDiversity.com Software Engineer _______________________________________________ Visit http://www.mimedefang.org and http://www.roaringpenguin.com MIMEDefang mailing list [email protected] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
