Comment 6 for bug 266278

I had the same bug -- and it also appears as Bug #266110 (sf1002486), Bug #266113 (sf1006797) and Bug #265938 (sf769484) from years ago and still hasn't been fixed.

Using sudo newlist in the command line works.

However, while the web interface does create a list (although with an error reported), it results in bouncebacks when subscribers try to send email to the list. The mail system returns this kind of message: "[Return Code 550] sid:_____ :: 5.1.1 <email address hidden>: Recipient address rejected: User unknown in local recipient table"
