Domain Parking - email forwarding old way

[Jedito]

I have some users parking domains over their main domain, in the past, all the emails sent to [email protected] were forwarded to [email protected], but with the new features of Cpanel that has changed, and the emails sent to [email protected] finish on the catch-all address of maindomain.com because there isn't an email address [email protected] created.

I want to still use the old way to handle parked domains and email forward, which changes should I do? is it possible to still do it without create email forwards through Cpanel?

Thanks in advance
