QMail help

[Anand Saokar]

Hi,

The document for Installing QMail and REMOVING Sendmail stated that:
15. Make qmail's ``sendmail'' wrapper available to MUAs:
       # ln -s /var/qmail/bin/sendmail /usr/lib/sendmail
       # ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail

but before this step /usr/sbin/sendmail is moved as
/usr/sbin/sendmail.bak !!! So, what is the use of linking qmail's
sendmail with actual non-existing sendmail executable?

Reply asap,
n'x,
Anand
