[Mimedefang] same message different results depending on sending mechanism

[Bill Friedman]

  sending again in case I forgot to send text-only first time.  I've 
done that many times..

Sent spam filled message via sendmail CL from an external machine and it 
got filtered and discarded as expected.

Sent same message via yahoo pop account to same sendmail machine and it 
got filtered but not discarded.  I replicated this several times.  The 
message is always filtered and discarded if I send via telnet CL either 
locally or remotely.  I noticed that in the first "CL" instance the the 
msgid included my gateway while in the second "POP" instance" it 
included the initial mail gateway.  But, in either case it's forwarding 
this message to an external user aliased from a local user.

.................
Sendmail is setup to only forward for "ourdomain" (not actual name) but
that doesn't seem to be the issue here as that's all that's being requested.
 mimedefang-filter is setup to not filter messages from local private subnet
machines, but, that doesn't seem to be the issue either, as in neither case
is their the ...no further action necessary... in the log entries.  Any ideas?
