interface, I now get:
Bug in Mailman version 2.1.8
We're sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of
traceback and other system information has been explicitly inhibited,
but the webmaster can find this information in the Mailman error logs.
But there is no information in the Mailman logs or the apache logs about
this error and my posts to the lists fail. Any pointers would be much
