Ubuntu list server issue?

[John Hupp]

Have any of you stopped receiving copies of your own posts to this 
list?  Mine stopped coming a day or two ago, both on this list and the 
Lubuntu list.  This despite the fact that my list mailman options still 
include "Receive your own posts to the list?  Yes."

And I did check my Spam folder -- they're not there.

I have been getting some replies to my posts, so I believe they are 
publishing -- just not back to me.
