Yes, the vmail user (uid 96) has permitions to write on 
dovecot-deliver.log and dovecot-deliver-errors.log.
The mail_login plugin is working normally, but at sporadic periods dump 
this kind of errors and refuse to deliver the mail.
I don't have the SELinux enabled in this machine, and don't have any 
warnings/errors in other log files.

Now, I haven't used the hg repository sources, but I could try with the 
last version...

Thanks,
