Any message that had over a certain amount of replies under the header will be cut off. This is set by the list administrators.

Also, the maximum allowed message size on any of our Mailman servers is set to 3 mb with any that are over 40kb being held for moderator approval. I'm not sure if this is configurable or not, but I don't think it is.

You can email help at uw.edu if you have specific questions and that will automatically open an RT ticket which will be routed to the proper help desk folks.

Hope that helps!
