Not only would I have to change all the names but I would have to list 200 files to search. If this change were made I would only have to search the right file and that file is the same structure as a standard passwd file.

This would make my life a lot easier in migrating to Dovecot. And it should be really easy to implement. Here's how linuxconf does it:
Password files are placed in the /etc/vmail directory as follows:
/etc/vmail/passwd.domain1 /etc/vmail/shadow.domain1 /etc/vmail/passwd.domain2 /etc/vmail/shadow.domain2
The password and shadow files are exactly the same format as the /etc/password and /etc/shadow files. The user name within the files would be the %n part of the email address passed to authenticate with.
Basically the password file names are /etc/vmail/passwd.%d with the user withing the file being %n.

It also makes merging several servers with separate passwd/shadow files into one virtual system because all you have to do is copy their existing passwd/shadow files into the /etc/vmail directory and rename them with the domain at the end.
So - wouldn't that be easy to add? Sure would make migrating easy for me.
Not commenting on the idea, but:
From the Dovecot Wiki: http://wiki.dovecot.org/moin.cgi/Authentication
"Dovecot 1.0-tests support defining multiple password databases, so that if password doesn't match in the first database, it checks the next one. This can be useful if you want to easily support having both local system users in /etc/passwd but also virtual users..."
Using this you could implement what you describe, with one small exception that usernames would have to be renamed in your passwd files to their appropriate user@domain form. I think that it is good practice to name your users with the complete name in the passwd file.
