No - you must reconfigure your MTA (Mail Transport Agent)

I believe Exim is an MUA (Mail User Agent). According to the info you
posted in your first email :

>> 6187 root 0 3.0 0.5 sendmail
>> 6163 root 0 2.9 0.5
>> /usr/sbin/exim-MCS-MCP-MCremote_smtpmx2.mail.yahoo.com219R55Q-0003AL-00
>> 6182 root 0 2.9 0.5 sendmail
>> 6190 root 0 2.9 0.5

Sendmail seems to be active and is probably acting as your MTA.


(MTA actually sends the mail to its destination system, MUA displays
mail to the user, MDA, "Mail delivery Agent" puts the mail in the user's
mail box once the mail has arrived on the user's system.)


You must reconfigure your sendmail.mc file and regenerate your
sendmail.cf file


To stop sendmail:  (do these as root)
service sendmail stop

The edit sendmail.mc as noted in my last two emails

Then (as root) regenerate sendmail.cf
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

And restart sendmail
service sendmail start
