Take a look at http://www.orbs.org/otherresources.html
First priority - throw that sendmail.cf into the dustbin and do an rpm --erase
linuxconf (with which you clearly config'd your sendmail - linuxconf generates
broken versions of 8.8.7 rulesets, making your system highly insecure).
Use the sendmail.mc file to regenerate sendmail.cf (you have to install the
sendmail-cf-8.9.3.rpm first, for this)

sigh ... this is a fscking FAQ at http://www.sendmail.org/faq (one of the top 5
most frequently asked questions abt sendmail ...)
