error msg after upgrade to 2.2.6

[Mark Nienberg]

I recently upgraded from 2.2.4 to 2.2.6 using the rpm's on the ftp 
site.  It was totally painless (I really appreciate the rpm format), but 
now when I compose and send a message from imp I get an entry 
in my apache error log that says:

sh: /sendmail: No such file or directory

I'm not trying to attach a file to the message.  Everything seems to 
work fine in spite of the error, the mail is sent.  Is there something 
more I need to do or should I just not worry about it?  The webserver 
is apache 1.3.14-3 on RedHat 7.0 and php is 4.0.3pl1-1.  Thanks,
