[Dovecot] Patch for dovecot 1.2.16 (and .17) for vpopmail module

Hi Timo,

I love dovecot but I love also vpopmail and its functions for manage user limits (via vmoduser). Unfortunately in dovecot 1.2.x auth default set to use "vpopmail" is unable to apply this limits. Only if used with checkpassword limits works fine but in the dovecot.log only user (without @domain) is logged.

So, based on the code of dovecot 2.0, I have created this very simple patch that correct this bug.

Thanks for consideration
