Yep, we're doing it.  I think that Eric may have found the cause of your
problems.

We do it using Exim's Perl support (performance - we've heard of it...)

I'll spare you a cut-and-paste of our config, as it's a little over
complex (support various authentication sources and methods), but the
PasswordCrypt module should make it fairly straightforward.

Try:

perl_at_startup = do '/path/to/exim.pl';

Where exim.pl is:

    use lib '/path/to/vmail-sql-lib/';
    use PasswordCrypt;

    sub check_pw {
        $password = shift;
        $hash = shift;
        if (PasswordCrypt::authenticate($password,$hash)) {
            return "yes";
        } else {
            return "no";
        }
    }

Then in your authenticator, something like:

fixed_plain:
    driver = plaintext
    public_name = PLAIN
    server_condition = ${perl{check_pw}{$3} \
        {${lookup mysql{select password_hash from domain \
        where domain_name = '$2'}{$value}fail}}}
    server_set_id = $2

fixed_login:
    driver = plaintext
    public_name = LOGIN
    server_prompts = "User Name : Password"
    server_condition = ${perl{check_pw}{$2} \
        {${lookup mysql{select password_hash from domain \
        where domain_name = '$1'}{$value}fail}}}
    server_set_id = $1

Let us know if you're still having trouble.
