Jeff, This can happen for several reason.
1) If you are on a mailing list and someone sends an email to you and the mailing list, there will be 2 emails. 2) If the message is queue on the server and the connection is interrupted before the client gets a reply to the quit command from the server the remote server will resend the message. 3) There are two instances of Dovecot running on different hosts. You might increase the timeout in spamdyke. This is all I can think of now.

He reported that with these very large emails he's getting multiple copies with a new copy coming every couple of hours. I checked his inbox and these are identical complete emails except for the 'part' codes withing the email body. It seems as if gmail is not getting the proper message received response from out QMT mailserver and, as a result, resend the email. Has anybody else seen something like this? I don't think it's a timeout on our end because the emails are complete. Nor is it a size issue since we have databytes set to 60 MB. Any ideas on what I should look at? Regards, Jeff Koch
