The alias is expanded and invoking the wrapper which is invoking the
'post' script which says the list isn't found.

Two questions: Do other lists that work invoke the same wrapper
(/var/mailman/mail/mailman)?, and what do you see if you look at the
above with something that shows 'transparent' characters?

Here again, the 'post' script can't find the list. I'm grasping, but
either the wrapper invokes a post script from a different installation
than /var/mailman (not likely), or there is a transparent character in
the list name in the pipe in the alias. I can't off hand think what
else it might be.

What happens if you manually give the command

python /var/mailman/scripts/post its-agp < /dev/null

If working properly, there should be no error from the command and no
entry in the error log, but there will be messages in the post, smtp
and probably smtp-failure logs.
