bm 3.8 is setup to proxy for gw 6.5 on another server on same subnet...

email transactions generated with telnet to the GWIA work fine, but the
same transaction to the BM mail proxy drop connection after "mail
from:<a@bb.com>" (have tried other addresses...) here's the session in
telnet

BM sample #1 --------------------
220 Service ready
helo mail.bb.com
250 mail.spectrum-tx.com OK
mail from:<a@bb.com> <-----(connection dropped)

BM sample #2 --------------------
220 Service ready
helo mail.bb.com
250 mail.spectrum-tx.com OK
mail from:<>
250 OK Requested mail action completed
rcpt to:<(me)@(DOMAIN).com>
501 Command syntax error <-----(must helo again)
quit
