Zmailer RFC822 parser barfs on null (<>) addresses

Got a note from Eric Allman ponting out that one of our machines running
ZMailer was complaining about null return addresses.  According to RFC822 and 
RFC1123 this is not optional.  I have not had a chance to look at it yet,
and won't get a chance until after returning from USENIX.  Eris'c note
is attached below.

The error message shown below seems to indicate that your mail
system doesn't understand the null return address.  This syntax
is required by RFC 821 and 1123.  I suggest you forward this
bug to your vendor as a VERY HIGH priority item.
