How many messages are in your inbox? I don't know what is causing this error, only two things I can think of: 1) Too many messages in your inbox (although I've got hundreds on my notebook where I wrote the class and it didn't complain. 2) One of your messages is messed up or different in some way. I'd backup my inbox and then delete the messages a dozen at a time, try readmail after each delete until the message stops (hopefully). Then reload the whole lot and look closely at the latest deletes.

Sorry I can't be of any more assistance at the moment but I've not had any problems with the class (or any reports of this problem). I'd like to know if and how you kill this problem.
