actually it looks like, nobody uses passwd-file like you do :)

The doc at http://wiki.dovecot.org/AuthDatabase/PasswdFile would lead to 
your assumption of operation, that is:

+ you auth using user at domain
+ look up the user in the domain-specific file without domain
+ but you don't overwrite "user", hence, further processing should have 
the domainin %d

Could you verify that the domain gets stripped by setting mail_debug, 
auth_verbose and auth_debug?

This page http://wiki.dovecot.org/VirtualUsers catches my eyes:

"In the above examples users are expected to log in as "user at domain". 
Their mail is kept in their home directory at 
/home/<domain>/<username>/Maildir.

The usernames in the passwd and shadow files are expected to contain only 
the user part, no domain. This is because the path itself already 
contained %d to specify the domain. If you want the files to contain full 
user at domain names, you can use %0.d instead of %d."

This is exactly what you want, IMO.

These pages also describes your idea:
