dovecot - Aug 2010 - TTY=unknown

I'm wondering if TTY=unknown should be consider as a warning or error.
I'm busy perfectioning the organisation's mail server. I want it to run
without any warning or error message.

==> /var/log/auth.log <=Aug 12 11:37:15 h1690641 sudo:     mail :
TTY=unknown ; PWD=/var/spool/postfix ; USER=root ;
COMMAND=/usr/lib/dovecot/deliver -f sender at domain.com -d receiver

Thanks in advance,

Frank

Dovecot has no TTY. This is normal.
