AIX must contain no .forward files.

The .forward file allows users to automatically forward mail to another system. Use of .forward files could allow the unauthorized forwarding of mail and could potentially create mail loops which could degrade system performance.

Search for any ".forward" files on the system using command: # find / -name .forward -print

If any ".forward" files are found on the system, this is a finding.

Run the following command to remove all ".forward" files on the system: # find / -name .forward -exec rm -rf {} \;
