If you have an email address called sales@mysite.com and you wish for all email from sales@myothersite.com to be sent there, then you can simply create a domain alias in helm without doing anything else and the email will go there automatically.
To do this:
1) Make sure you have an email setup for your main domain (sales@mysite.com) to where the left-side (the "sales@" part) matches the address you need forwarding from.
2) Add a domain alias for myothersite.com under your main domain.
The alias in the control panel should look something like:
myothersite.com >>>>> mysite.com
