This seems to be a recurrent problem with Mac OS X

See your own post at

Also see the post at
and response at

For additional info see

You can also search google with

"errno 22" "config.pck.last" site:mail.python.org

and find all the above plus more. Note that although in all these posts
the error may arise differently, the actual error in every case is

   File "/usr/local/mailman/Mailman/MailList.py", line 497, in __save
OSError: [Errno 22] Invalid argument: 

and the platform is always Mac OS X. I don't know the answer, but as
mentioned in more than one of the posts in the archive, see

Beyond what's in that FAQ, this list probably can't help you much with
Apple's Mac OS X Server installation. You might have more success
persuing Apple support resources.
