ListProc at KU - Common errors and problems for list subscribers

I have been getting messages from a list for quite sometime. I just tried to post my first message to the group and am getting an error message stating that I am not subscribed. How can that be, if I am getting messages?

This is usually caused by a mismatch between the email address under which you are subscribed and that with which you are posting messages. When you subscribe to a list ListProc takes your e-mail address for the contents of the From: header in your subscribe message to ListProc(unless the owner of the list adds your address on your behalf). If some aspect of your e-mail address has changed, say for instance you now have an alias or your Internet provider changed your address from myemail@server.com to myemail@mail.server.com, ListProc will not find a match for you in its subscriber file.
The easiest way to resolve this situation is to contact the owner of the list. If you saved your Welcome Message, that person's address is listed there. If not, try sending a message to OWNER-listname@ku.edu. Replace listname with the name of the list you are having trouble with.
