@pygy_ So, i just checked (because you got me curious too)...and the Zoho Mail Lite plan (I'm U.S. based, so i pay $1 USD per user per month) does indeed have the catchall feature available. But, please note, it is present within the admin console...so not within, say, the user's mailbox. If you were a single user, that would not be an issue...but i think i recall you saying about needing for your family...so not sure if/how the set up a catchall at the admin console level interacts with each user's email address/identity...hmmm...Likely it only activates assuming, say, amazon@your-domain.net is not being used by one of your family users...but it merits a little more research on your own, if you in fact use this feature alot. Good luck!
