[Mailman-Users] Re: Size limit leads to rejection instead of moderation

The size limit, General Options -> max_message_size will only result in a message being held. These messages are being rejected for some other reason. Check Mailman's vette log and/or the rejected message for the reason.

If that doesn't reveal the reason, also check your MTA logs and configuration. MTAs are usually configured to reject or discard huge messages (I think Postfix defaults to 50MB), and that would happen before getting to Mailman.
