OK. So there are two issues. The first is that the attachment is sent in 67 or however many partial attachments and the second is that Mailman is sending 67 copies of each partial message instead of just 1.
The first issue is due to the sending MUA (user's email client) breaking the large attachment across multiple messages (presumably Content-Type: message/partial) which have to be reassembled by the recipient's MUA. This issue is strictly due to the sending MUA and has nothing to do with Mailman. Note that splitting messages into multiple message/partial messages is a bad idea in general, both for security because most virus and spam scanners work only with the individual partial messages rather than the reassembled content, and because many MUAs don't know how to reassemble the partial messages into a complete whole. The second issue of Mailman sending multiple copies of each partial message is a bug somewhere. It may be something in the cPanel Exim Router/Transport definitions for Mailman or in cPanel Mailman or in Mailman itself. It is hard to say without seeing server logs, but if you could send a message with an attached PDF (preferably not TOO big) in the same way it's sent to Mailman to [email protected], I can do some testing. You probably do not have access to any server logs. If I don't find anything, you'll have to take this up with your cPanel host.
