Hotmail - Sender appears as (Unknown) and (No Subject) line
Having a problem with Mailman and Hotmail.
The sender appears as (Unknown) and the subject line simply says (No Subject).
All other e-mail providers are fine and show the correct Sender and Subject line.

The "Mailman and" is redundant....

That is pretty strong evidence that Mailman is fine and Hotmail is broken. Also, the relevant Subject and From header fields appear to be correct (without the actual address, I can't be sure -- it seems very unlikely that the list's address is broken, though).
Here is the Message Header from the Hotmail recieved e-mail (I've removed our email details, IP etc to hide our privacy):
Unfortunately, as I received it from the Mailman mailing list, the header is broken from the very first line (there are line breaks resulting in mail header syntax errors, both in that first line and in several other places). Most likely this is due to your mail client, or due to cut and paste, but if this is what Hotmail is seeing, it's a mess. But it's not Mailman's mess, or the other mail clients would also be reporting obvious breakage. It's happening somewhere after leaving your host, and it would appear that all later hosts are under Hotmail control (it's hard to be confident without the redacted information).
Looking only at the headers that should supply the missing information:
From: <E-MAIL REMOVED> To: <E-MAIL REMOVED> Subject: Lockout, Salmon Fishing In The Yemen & more! Competition & Picture Quiz!
Assuming the above are formatted as received by Hotmail, I see no excuse for not displaying the author and subject fields properly.
Sender: E-MAIL REMOVED
The Sender field confuses Microsoft Outlook, but the symptom of the confusion is that horrible "From: xxx on behalf of yyy" header.
Maybe somebody else has heard of this before and can suggest a workaround, but I really don't see anything that anybody but Hotmail can do anything about.
