Strange Mailer Activity

I am getting a lot of strange bounces in my inbox.  I checked to make sure
that my mailer wasn't running as an open relay.

Running #ps aux | less

I see some possibilities of processes running sendmail.  Is
./s5N5AsEo003358 the file that is calling sendmail?

root  6961   0.0  0.3 12864  5540  -  I    12:24PM    0:00.18 sendmail:
./s5N5AsEo003358 user open (sendmail)

 There are also a lot of "to" entries in my maillog that don't look like
they are being sent from any of my users.  Also, I no longer use my server
as a relay of any sort.  Everyone is now using gmail to send, and my
friends have custom email domains that I host incoming mail for.  This mail
is no longer spooled on  my server.  It is just redirected to their (and
my) google accounts.
