Verification Email Not Received for Aster-to-Aster Auto-Forwarding

[User-green]

I turned on auto-forwarding from Aster to Tuta, and the verification email arrived, so now all emails are being properly auto-forwarded from Aster to Tuta.

However, I have turned on auto-forwarding from Aster to Aster, but the verification email is not arriving at all.
