This is telling you that your /var/run directory belongs to bin (user
ID 3), and that only user bin can write to the directory.  My sendmail
shows:

-r-sr-xr-x  3 root  bin  266240 Dec 11 18:19 /usr/sbin/sendmail

This is 3.0-CURRENT as of some time ago.  I suspect that your
permissions are different: either your sendmail doesn't belong to
root, or it doesn't have setuid permission (the s in the permissions
string).  You can fix this in a number of ways: set sendmail
permissions as above, or if your sendmail is running happily without
being root, you could change the permissions of /var/run to 775 (if
your sendmail is group bin) or 777 (otherwise; maybe not a good idea).
On the other hand, touching /var/run/sendmail.pid won't work past a
boot, since the boot process removes everything there.
