I am having a similar problem between a XENIX running machine and my VAX 
mail server running Mt. Xinu 4.3 BSD.  I think that I can describe the cause 
of the problem in detail. (If I go astray in this explanation, *please* correct
me)  I can not, however, provide a solution:

The problem that I am having is caused by an improper From (no colon) line
being received by rmail on the BSD machine.  A proper From line is composed 
of an address followed by a date.

From chris@ADMS-RAD.Unisys.COM Mon Aug 13 15:01:00 1990

When mail is sent via uucp something (uux??) should tack a "remote from"
piece on the end of the From line.  A correct example looks like:

From ADMS-RAD.Unisys.COM!chris  Mon Aug 13 15:00:46 1990 remote from imagine

Upon receiving this, rmail prepends the hostname given in the "remote from"
entry to the existing From path and sends the whole thing to sendmail (or
another transport agent) like this:

/usr/lib/sendmail -ee -fimagine!ADMS-RAD.Unisys.COM!chris -i 'tim@gvlf9.GVL.Unisys.COM'

The somewhere entry is created when rmail receives a message that doesn't
have the "remote from" portion of the From line.  The rmail source is written
such that the path of any mail recieved without a "remote from" appended
to the From line will be given to sendmail in this format:

Here is the From line:

From uucp@ls.com  Sun Jul  1 20:10:31 1990

Here is the sendmail command line:

/usr/lib/sendmail -ee -fsomewhere!uucp@ls.com -i 'news'


Given this expanation of the problem, can anyone:
 A) 	Offer any insight as to where the "remote from" comes from and why 
	it isn't being tacked onto the mail that I am receiving from this 
	system??

 B)	Tell me that I am barking up the wrong tree and point me in the right
	direction.


Thanks--
