[Dovecot] dovecot not working with some vpopmail passwords

[radus at smartpost.ro]

Hello.

I tried installing dovecot on a server that relies on vpopmail
authentication using $1$ MD5 algorithm and it didn't work.
Please fix this for the next release.
Attached is a patch, please be carefull with the line wrapping.

Radu
