Comment 9 for bug 102947

Hi there,
This is just to confirm that this is still happening in 9.04. It's purely maildrop issue, fetchmail has nothing to do with it. You can test it by calling:
maildrop -d <username>
It will issue the error message. Looks like maildrop was compiled to be a part of courier. As mentioned above Courier-authlib is installed, but not running.

Nevertheless the email is still delivered. So, it can be probably ignored or if it annoys you, change fetchmail to use procmail instead...
