But that's incorrect, isn't it?  Could you check the reasoning below?

o  Given:  This system is FC5 with sendmail 8.13.6. (MS 4.54.6).

o  MailScanner.conf has:
      MTA = sendmail
      Lock Type =

o  Therefore, according to the comments, this should result in "posix".

o  "posix" is, indeed, the desired and expected outcome for this system
   (isn't it?).

o  BUT "maillog" is reporting
      ... MailScanner[26259]: Using locktype = flock


The comments say I should end up with "posix".  Maillog says I'm getting
"flock".  So something somewhere (possibly including my understanding!) is
incorrect.

Help!
