Yes, email attachments take up a lot of space.

But anyone who tries to auto-delete my attachments will never get my patronage.

Why do you want to cripple email to create a free service? This seems like a race to the bottom, with very little upside for you.

Not everyone is willing to pay for mail service for custom domains. Paid email services already costs near or below disc storage prise.

Limiting attachments - the only possible way for free ADs-based alternative.
