favicon.ico is missing???

[Gerry Doris]

I have been seeing large numbers of httpd errors in the
ssl_access_errors logs.  

These seem to indicate that a file called favicon.ico is not being found
and appear to be occurring when MailScanner is being accessed.  I've
located this file (or one by the same name) in several locations but
none of them have anything to do with MailScanner.

Is favicon.ico used by MailScanner or MailWatch???
