[opendmarc-users] How to exclude domain from reporting?

[Niklaas Baudet von Gersdorff]

One of yandex.ru's mail for reporting is dmarc-rua at yandex.ru,
see:

  ;; ANSWER SECTION:
  _dmarc.yandex.ru.	3526	IN	TXT	"v=DMARC1; p=none; fo=1; rua=mailto:dmarc_agg at auth.returnpath.net,mailto:dmarc-rua at yandex.ru; ruf=mailto:dmarc_afrf at auth.returnpath.net"

Every time OpenDMARC send a report to that mail, the message is
bounced because the mailbox is full. I already contacted
postmaster at yandex.ru but haven't got any response yet.

What's the easiest way/best practice to prevent sending reports
for the domain yandex.ru at or (even better) prevent sending
reports to dmarc-rua at yandex.ru in particular?
