"mailscanner reload" for Solaris?

[Jeff A. Earickson]

Hi,
    My script (before yesterday) used pgrep and/or pkill.  "pgrep
MailScanner" gives all of the process numbers.  For a reload, I only
wanted the group leader.  I contemplated the "-o" option of pgrep/pkill
to only give me the oldest process to HUP.  But it makes more sense
(to me anyway) to use the info in the MailScanner.pid file.
