logwatch broken after replacing sendmail with postfix

[G H]

i don't know, the script contains:
          open(OUTFILE,"|$Config{'mailer'}") or die "Can't execute 
$Config{'mailer'}: $!\n";


for what i understand, it does not search sendmail in /usr/lib.
On antoher solaris machine:
gyptis # pkgchk -l -p /usr/sbin/sendmail
Pathname: /usr/sbin/sendmail
Type: symbolic link
Source of link: ../lib/sendmail
Referenced by the following packages:
         SUNWsndmu
Current status: installed


thanks for your reply,
