dovecot creates folders for users not in the database

[ubuntugeek2010]

Hi,

I'm having an issue where Dovecot creates folders and delivers mails to users who are not in my virutal users table. Mostly I see are typing mistakes. How can i tackle this? I have my dovecot service running on Ubuntu 10.04 server edition LTS.

Regards
UG

Dovecot doesn't deliver emails - this is done by your MTA (Postfix, Sendmail, Exim,...). Any errors in your mail log?

Actually postfix is not doing that. I have configured to use the Dovecot LDA to do the job. Puttting the following in the master.cf

dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

and the following

postconf -e virtual_transport=dovecot
postconf -e dovecot_destination_recipient_limit=1

I do not have any error messages on my mail.log. That's why it is strange
