When you create a parked domain on top of an existing one you get an output like this:

Parked Domain Maintenance

Parked Domain Additions

Nameserver ips for domain2.com are: 64.62.161.48,69.57.129.132,69.57.129.131
Created DNS entry for domain2.com

Setup Mail forward domain2.com -> domain1.com
Setup domain2.com OK
Adding httpd.conf entry for domain2.com to point to domain1.com



But the problem is that there is no such thing created as a mail forwarding from domain2.com to domain1.com!!!!!
