The maildrop-1.5.2 ebuild configures the mysql config dir as /etc/maildrop/maildropmysql.cf, but the ebuild installs it in /etc. This causes massive confusion as to why it won't work. :) Reproducible: Always Steps to Reproduce: 1. 2. 3.
Just for people's reference, this causes a screwy: Invalid user specified. error from maildrop. Hopefully this will help.
fixed in CVS.
