4.51.5 scanning messages multiple times

Hash: SHA1

Have you run MailScanner in debug mode? Does it produce any errors? 
There are reasons why messages can be dropped from a batch, but there 
are very few with sendmail, it's only Postfix which does it 
(intentionally, to allow scanning later).

If you are using sendmail 8.13 and upwards you should use Lock Type = 
posix, before 8.13 you should use Lock Type = flock.

Differing locking will cause problems like this.

You say the 4 boxes are setup identically, but they are behaving 
differently, which tends to imply they aren't actually the same :-)
