Bug 35363

	Sendmail 8.12.x has an implementation bug in the milter
	code that causes the milter daemons to fail when they
	are bombarded with 20-30 messages from a mail server.

	This problem was recently disscussed on the AMAViS mailing
	list and comp.mail.sendmail

Fix: Apply the following patch:
How-To-Repeat: 	Install the port and configure it to use a milter daemon,
	then bombard it with 20-30 messages from another mail
	server.
