Can I stop spam bounce reports?

Question

Email

Hello everybody!
From time to time, users' mail clients receive non-delivery reports. They come in huge numbers (1-2 thousand letters). Of course, the users themselves did not send letters, especially in such quantity. Looks like the spammers are just spoofing the return address. Most often, these reports come during non-working hours, that is, after 18:00, or on weekends. Whether it is possible to struggle with it somehow?

In general, this is a serious problem, they obviously spoil your domain reputation. You need to properly configure DMARC, extend it to a subdomain so that it makes no sense for them to send emails. And check the site for viruses.
