I am having trouble getting mx smtp server to accept a null
address from other hosts during the smtp session.

This session originates from host sam in the local domain. It connects
to host MNSMC1 which is a 3100/80 running 6.5 CMUTEK and MX v 3.1C

Here is the smtp session:

220 MNSMC1.MNSMC.EDU MX V3.1C SMTP SERVER READY AT MON, 09 NOV 1992 10:21:03
sam: HELO sam.mnsmc.edu
250 Hello, sam.mnsmc.edu
sam: Mail from: <>
501 Invalid Address: <>
sam: 501, unexpected response from remote smtp server 501

Initially I thought that sam was trying to pass off mail which
had a null, and therefore invalid address. However, in reading
rfc 821 - SMTP and after looking at the message on the sending
system the message is a undeliverable mail notification message
which should have a null address to prevent looping.

However, MX is erring out on any message with a null address. Can
MX handle such an address, do I need to upgrade or change my
configuration to enable this to happen?

Thanks for your assistance, Dan.
