Sendmail 5.61++/IDA-1.2.8

Problem:
	my sendmail puts source routes in the From_ line for
	mail bound for local delivery..

How can I get sendmail to convert the 822 Source routes into at least
a ! path, or keep in a user@host form.  Even when the originating host
is fully qualified via a nameserver, if it goes through an
intermediate machine, sendmail tacks on another part to the source
route..  The end result is that my From_ lines look like a mess.
(Yes, my From: lines are intact..)


Here is an excerpt from deliver.c for local delivery:

	/* rewrite from address, using rewriting rules */
	expand("\001f", buf, &buf[sizeof buf - 1], e);
	(void) strcpy(tfrombuf, remotename(buf, m, TRUE, TRUE, FALSE));

	define('g', tfrombuf, e);		/* translated sender address */
	define('h', host, e);			/* to host */
	Errors = 0;
	pvp = pv;
	*pvp++ = m->m_argv[0];

	/* insert -f or -r flag as appropriate */
	if (FromFlag && (bitnset(M_FOPT, m->m_flags) || bitnset(M_ROPT, m->m_flags)))
	{
		if (bitnset(M_FOPT, m->m_flags))
			*pvp++ = "-f";
		else
			*pvp++ = "-r";
		expand("\001g", buf, &buf[sizeof buf - 1], e);
		*pvp++ = newstr(buf);
	}
