This has nothing to do with MailScanner.

Check .forward file ownership and permissions.

>From sendmail.org...

Beginning with sendmail 8.9, these checks have become more strict to
prevent users from being able to access files they would normally not
be able to read.  In particular, .forward and :include: files in unsafe
directory paths (directory paths which are group or world writable) will
no longer be allowed.  This would mean that if user joe's home directory
was writable by group staff, sendmail would not use his .forward file.
This behavior can be altered, at the expense of system security, by
setting the DontBlameSendmail option.  For example, to allow .forward
files in group writable directories:

        O DontBlameSendmail=forwardfileingroupwritabledirpath

Or to allow them in both group and world writable directories:

        O DontBlameSendmail=forwardfileinunsafedirpath

Items from these unsafe .forward and :include: files will be marked
as unsafe addresses -- the items can not be deliveries to files or
programs.  This behavior can also be altered via DontBlameSendmail:

        O DontBlameSendmail=forwardfileinunsafedirpath,
                forwardfileinunsafedirpathsafe

The first flag allows the .forward file to be read, the second allows
the items in the file to be marked as safe for file and program
delivery.
