freebsd stable - Feb 2004 - no mapping in /etc/mail/mailer.conf

Hi all, 

I have had following message in my periodic daily output for several days:

Removing stale entries from sendmail host status cache:
purgestat: no mapping in /etc/mail/mailer.conf

But I did no changes in my smtpd (qmail) configuration. It works well, both the
local and the remove delivery seems to work ok. My /etc/mail/mailer.conf
contains the following lines (comments are sniped):

sendmail        /var/qmail/bin/sendmail
send-mail       /var/qmail/bin/sendmail
mailq           /var/qmail/bin/qmail-qread
newaliases      /var/qmail/bin/newaliases

File permisions seems to be ok too:

-rw-r--r--  1 root  wheel  324B Feb  9 11:01 /etc/mail/mailer.conf

Can I silently ignore this message? Oh, yes, my system is: 

FreeBSD hilbert.chtf.stuba.sk 4.9-STABLE FreeBSD 4.9-STABLE #0: Wed Feb 11 
18:23:18 CET 2004     root@hilbert.chtf.stuba.sk:/usr/obj/usr/src/sys/HILBERT  
i386

Be free to ask for more information... Thanks for advices. 

Jozef Babjak.

Either add this to /etc/periodic.conf:

daily_clean_hoststat_enable="NO"

or add this to /etc/mail/mailer.conf:

purgestat	/usr/bin/true

(assuming qmail doesn't have an analogous command to purgestat)
