serious flaw in zmailer 2.99.23

[James MacKinnon <jmack@in.edmonton.ab.ca>]

I've just noticed that 2.99.23 does some serious damage to both the 'From:'
and 'To:' lines for the following case:

following the older localnames behavior in standard.cf:

if [ -f $MAILVAR/db/localnames ]; then
    relation -lt unordered -f $MAILVAR/db/localnames -d pathalias -b thishost


I have the following entries in db/localnames for equivocal hosts on this 
machine:

IN.Edmonton.AB.CA
laddie.Phys.UAlberta.CA


Local transport occurs when I send from laddie to the IN.Edmonton.AB.CA
domain. The router log shows:

<96Jan1.132601-0700mdt.31145+1@laddie.Phys.UAlberta.Ca>: address: jmack
<96Jan1.132601-0700mdt.31145+1@laddie.Phys.UAlberta.Ca>: file: 31145 
James MacKinnon <jmack> => jmack@IN.Edmonton.AB.CA
<96Jan1.132601-0700mdt.31145+1@laddie.Phys.UAlberta.Ca>: address: 
jmack@IN.Edmonton.AB.CA

But when the message is delivered via a local mailbox action, the headers get
re-written in a totally unacceptible form:

>From jmack@laddie.Phys.UAlberta.Ca  Mon Jan  1 13:07:41 1996
Received: by laddie.Phys.UAlberta.Ca id <31142>; Mon, 1 Jan 1996 13:07:31 -0700

X-Sender: jmack@laddie.phys.ualberta.ca
To:     James MacKinnon <jmack@.edmonton.ab.ca>
Subject: test 2.99.23


Somewhere the 'IN' (or 'in' part of the domain name (case doesn't matter)
are being stripped off, and I'm left with a bogus '<jmack@.edmonton.ab.ca>'
string.

I had thought of the 'IN%' strings in canon.cf for the VMS kludge, but after 
stripping them out, the problem still remains.

I had to revert back to 2.99.15 (currently running) which is fine (no 
corruption in this regard). 

Any ideas Matti?
