maildrop 1.3.4 keeps telling me my virtual maildir users are invalid, but I can't spot why. Can someone give me a hand, or failing that, a boot to the head?

I'm trying to set up maildirs for virtual users in domains I host, intending eventually to let users retrieve mail via courier-imap.

I've installed maildrop 1.3.4 using openbsd's ports tree, with make modified to add --enable-userdb and a short list of --enable-trusted-users='...'.

Changing the config further to --enable-restrict-trusted=0 has no effect on this problem. Neither does presence or absence of suid/sgid mode bits on /usr/local/bin/maildrop and friends.

The umbrella user, 'vmail', homedir and passwd entry are set up as follows:

drwx------ 2 vmail vmail 512 Apr 29 00:21 /home/vmail/ vmail:*:1002:1002:Virtual Mail User:/home/vmail:/bin/ksh

In addition, my userdb is set up as follows. In /etc/userdb/default:

vmail uid=1002|gid=1002|home=/home/vmail|shell=/bin/ksh|systempw=* 1002= vmail

And in /etc/userdb/host.example.com:

use...@host.example.com uid=1002|gid=1002|home=/home/vmail|mail=/home/vmail/host.example.com/user1|systempw=*

I've created the referenced maildirs with maildirmake in the domain subdirectory of /home/vmail:

drwxr-x--- 3 vmail vmail 512 Apr 29 00:22 host.example.com/ drwx------ 5 vmail vmail 512 Apr 29 00:22 host.example.com/user1/ drwx------ 2 vmail vmail 512 Apr 29 00:22 host.example.com/user1/cur/ drwx------ 2 vmail vmail 512 Apr 29 00:22 host.example.com/user1/new/ drwx------ 2 vmail vmail 512 Apr 29 00:22 host.example.com/user1/tmp/

However, I still get the following error:

% cat blah | /usr/local/bin/maildrop -d use...@host.example.com /usr/local/bin/maildrop: Invalid user specified.

A couple days of poring over mailing list archives, examples, and reading man pages + FAQs haven't led me to understand -why- the user is invalid.

Can you spot the mistake in my configuration above? Or am I not providing data that greater experience considers useful for spotting my mistake?

Or should I look at installation configuration for a fix instead?
