[Mimedefang] Strange duplicate mail

[James Miller]

Hello everyone,

I'm running MimeDefang 2.35 and SA 2.55 w/Sendmail 8.12.9.  Occasionally
(more an more frequently) we are getting duplicate messages.  The duplicate
messages have the same message ID from sender; we assign a unique id to each
of the duplicates.

To test this I did the following:
telnet mailserver 25
HELO myserver.simutronics.com
MAIL FROM:<jimm at simutronics.com>
RCPT TO:<jimm at simutronics.com>
DATA
blah
blah
blah
about a page of data

<enter>
.
<enter>
QUIT

After the '<enter> . <enter>' it's taking 60-70 seconds to accept the
message.  I think some of the servers sending us mail are closing the
connection before we acknowledge receipt -- and later resends the message on
it next queue run -- though we did, in fact, get the message.

I haven't found a way (if there is) to tell mimedefang not start processing
a message until after it's been completely received.

And I'm not sure how to better test and find out what the problems are and I
would appreciate any suggestions.


Thanks,
Jim
