I want to replace RAV antivirus on my red hat server, and i want to install 
postfix+mailscanner+clamav

Postfix is working fine.
Clamav is ok.

But ...the mailscanner does not work
i have downloaded mailscanner 4.24-5 and installed
on my /var/log/maillog

...
Nov 21 14:33:01 mailna MailScanner[22594]: MailScanner E-Mail Virus Scanner version 4.24-5 starting... 
Nov 21 14:33:02 mailna MailScanner[22594]: Could not read executable /usr/lib/sendmail 
Nov 21 14:33:02 mailna MailScanner[22594]: Error in line 121, file "/usr/lib/sendmail" for sendmail does not exist (or can not be read)
...


i dont want to run sendmail, in fact i dont have sendmail , i have postfix running already.
what i need to put on this line(121) on the .conf file?


thank you and sorry about my english.
