Hi there,
I have a question concerning deleted domains. I deleted a domain (previous-domain.com) from my HestiaCP install. If I look in the exim4 mainlog it shows quit a lot of ‘dovecot-login’ authenticator failed activity with (non-existent) e-mail-addresses with that same previous-domain.com

Is there something I can or should do to prevent this from happening?
Thanks in advance!
