I've done a quick survey of the Suns available to me to see whether
sendmail updates the ps display.  The summary is:

   1) Require "/usr/ucb/ps w" at least.  /usr/bin/ps has no options
      that I can find to display the status of sendmail.

   2) Older versions of sendmail do not update the status.  8.6 does
      not update, 8.8.8 does.

   3) Solaris 2.5 and 2.5.1 have sendmail 8.6, 7 has 8.9.1, 8 has
      8.9.3.  Some 2.6 have 8.6, others have 8.8.8.  Presumably
      patches have beed applied.

On other OSs, AIX 4.1, 4.2, 4.3 have sendmail 8.8.4, 8.8.6, 8.8.8 or
8.9.3.  They all display the status in both SysV and BSD modes.
On AIX there is one ps command which handles both styles.

IRIX 6.2 and 6.5.4m through 6.5.10m have sendmail 8.8.8, 8.9.1, 8.9.3.
No status is available.  There do not appear to be any BSD-ish ps
options.
